Cd contamination increases the risk of diseases after consumption of grain crops with high Cd levels. Hyperaccumulators or accumulators have been widely used to bioremediate Cd-contaminated farmland soil. Studies report that aquatic hyperaccumulators or accumulators are rarely used in phytoremediation, or their phytoremediation efficiencies are low. A pot experiment was carried out to explore the effects of abscisic acid (ABA) on the Cd accumulation (phytoremediation) of emerged aquatic accumulator plant Nasturtium officinale R. Br. Abscisic acid application increased the shoot biomass, peroxidase (POD) activity, superoxide dismutase (SOD) activity, catalase (CAT) activity, and soluble protein content of N. officinale under Cd-contamination condition. The application of ABA at 5, 10, and 20 μmol/L increased the chlorophyll and carotenoid contents in N. officinale. The application of ABA also increased the shoot Cd content and shoot Cd extraction of N. officinale. The application of ABA at 1, 5, 10, and 20 μmol/L increased the shoot Cd extraction by 11.65%, 25.27%, 37.91%, and 58.52%, respectively, compared with the control. In addition, ABA concentration had a linear regression relationship with the root biomass, shoot biomass, root Cd extraction, and shoot Cd extraction. Correlation, gray relational, and path analyses showed that the root biomass, shoot biomass, root Cd extraction, root Cd content, POD activity, SOD activity, and soluble protein content were significantly associated with the shoot Cd extraction. These findings indicate that ABA application can improve the phytoremediation ability of N. officinale under Cd-contaminated flooded fields.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"44 2","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143689086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Metal-organic frameworks (MOFs), as a kind of adsorbent, have attracted great attention due to the large surface area, adjustable pore size, and high stability. In this study, a Zr-MOF, named MOF-525, was synthesized by using solvothermal method, and the adsorption performances of MOF-525 on two anionic dyes (methyl orange, MO and methyl red, MR) were investigated. Results showed that the obtained MOF-525, with the specific surface area of 2,613.91 m2 g−1, the total pore volume of 1.20 cm3 g−1, and the average pore size of 1.84 nm, exhibited high adsorption capacities for both MO and MR. The optimal pH value for MO and MR adsorption were 3.0 and 4.0, with the adsorption capacity of 854.30 and 629.67 mg g−1, respectively; in addition, the adsorption capacities for both MR and MO were increased with the increasing of SO42− concentration. The adsorption kinetics, isotherms, and thermodynamics results indicated the pseudo-second-order model and Langmuir (as well as Freundlich) could describe the adsorption processes of MOF-525 well, and the adsorption processes for both MO and MR were spontaneous exothermic reactions. Besides, the reusability experiment demonstrated that MOF-525 had significant adsorption capacity and good reusability for MR. In conclusion, the possible adsorption mechanisms of anionic dyes by MOF-525 involved hydrogen bonding, electrostatic attraction, and π-π interaction. These results illustrated that MOF-525 might be a potential adsorption material for anionic dyes removal from wastewater.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"44 2","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143689087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To further investigate its effects on particle growth behavior, this study employs numerical simulations, coupling the particle growth rate equation with a population balance model to systematically analyze the impact of various supersaturation distributions on particle growth. The results indicate that, in the axial direction, the closer the supersaturation peak is to the outlet of the growth tube, the more effective the particle growth, with a maximum increase of 10.20%. In the radial direction, higher supersaturation near the tube wall results in better particle growth at the outlet, with a maximum increase of 28.70%. A more uniform supersaturation field is found to promote particle growth. Conversely, when the supersaturation near the wall is relatively low, particles are less likely to be effectively activated, leading to restricted growth. Additionally, this paper explores the growth of fine particles under different supersaturation field configurations, demonstrating the generality of the observed patterns.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"44 2","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of activation temperature and nitric acid dosage on the mechanical strength and NH3-SCR performance were discussed. The results demonstrated that the catalyst CMZ-10-600, prepared at a calcination temperature of 600°C with a 10.0 wt % nitric acid dosage, exhibited the best NH3-SCR performance while meeting the mechanical strength requirements for industrial applications. The NO conversion ranged from 93.8% to 100.0%, and the N2 selectivity varied between 78.0% and 100% at a gas hourly space velocity (GHSV) of 5000 h−1 within the reaction temperature range of 150–250°C. The prepared catalysts were characterized using the scanning electron microscopy, x-ray powder diffraction, BET, NH3-TPD, and x-ray photoelectron spectroscopy (XPS), which elucidated the effects of the preparation method on the catalyst strength, physicochemical properties, and the NH3-SCR performance of the catalysts. The research results proved that the catalysts produced by this process exhibit good mechanical strength and catalytic properties, coupled with low raw material costs and a simple preparation technique, highlighting a promising prospect for industrial application.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"44 2","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, biomass-based cook stoves onsite data survey and experimental approaches were carried out to evaluate the performance of different cook stoves. Based on this feasibility research, it was shown that firewood accounted for 75% of the fuel type usage. The results of several studies and experimental performance testing indicated that the efficiency of cook stoves for 3-stone, lakech, mirt, gonze, tikikil, and pyrolysis stoves was 10%, 25%, 48%, 50%, and 76%, respectively. Merely 87 out of the total 1986 families with kebeles had improved cookstoves; the remaining households used 3-stone stove types. According to the study, the pyrolysis stove had the lowest fuel consumption rate and cooking time, while the 3-stone stove had the greatest fuel consumption rate and cooking time. The improvement stove reduced emissions, and the highest emission reduction stove was the gasifier stove, with a magnitude of 1.229 tons CO2/HH/Year.

Through the utilization of ANOVA, we were able to determine the key elements that impact the emissions of methanol gasoline from engines. Additionally, we validated the correctness of the experiment by employing the signal-to-noise ratio. The analysis focused on the combustion parameters of an engine that burns methanol fuel while maintaining low overall emissions. The accuracy of the numerical simulation was confirmed through the utilization of GT-power for numerical simulation and subsequent experimental validation. The findings suggest that when the engine operates at a load of 1200 rpm and 6 N m while consuming M85, there is a reduction in both conventional and unconventional emissions. M85 has a maximum cylinder pressure that is 18.7% more than pure gasoline. Conversely, pure gasoline demonstrates a power output that is 24.7% higher than M85. Additionally, M85 has a BSFCe that is 22.71% higher than gasoline. The addition of a methanol-gasoline mixture can effectively reduce the engine's exhaust temperature.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"44 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143112013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the adsorption capacity, cost, and environmental impact of five low-cost adsorbent materials: biochar, clinoptilolite, hydrochar, diatomaceous-earth, and crushed glass. Gravimetric analysis was used to determine the adsorption capacity of these materials for octamethylcyclotetrasiloxane (D4). The results were then used to conduct a technoeconomic analysis (TEA) and life cycle assessment (LCA), comparing the selected adsorbents with activated carbon (AC), a commonly used adsorbent for siloxane removal. The TEA revealed that the cost of LFG purification with clinoptilolite, biochar, and AC was $0.035, $0.034, and $0.033/m3, respectively, for the base case studied. The cradle-to-gate LCA showed that clinoptilolite had significantly lower carbon emissions compared with the other adsorbents, both per kg of D4 captured and per kg of adsorbent produced. The potential fate of siloxanes after adsorption was discussed, emphasizing the importance of proper treatment and disposal of spent adsorbents. Surface modification techniques were recommended to enhance the adsorption capacity and regeneration of clinoptilolite, potentially reducing cost and carbon emissions in LFG purification. These findings highlight the potential of low-cost adsorbents for sustainable LFG purification.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"44 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143111156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To expedite the processing of liquid waste stored in underground tanks in Washington State it is necessary to remove the significant dose contributor, 137Cs. Crystalline silicotitanate ion exchanger is currently used to remove 137Cs from the aqueous phase of Hanford tank wastes in preparation for vitrification at the Waste Treatment and Immobilization Plant (WTP). Improving the understanding of potassium impacts on ion exchange behavior of Cs will help in the operation of a critical component of one of the most complex treatment processes in the world today. Optimization of this process can result in significant cost savings and less waste production. Toward this effort, a series of batch contact tests varied in potassium concentration were conducted to look at the impact of potassium concentration on Cs distribution. Experimental distribution ratios (Kd) were compared to the distribution ratios predicted using the ZAM model. A significant underprediction of Cs capacity in the presence of potassium was seen with the existing model. A revision of the equilibrium constants was determined and provided a statistically better fit for determining the Cs Kd values in tank waste matrices.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"44 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2024-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ep.14535","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143111157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The technical components of the STIRPAT model were expanded upon to better understand the factors influencing the household consumption sector and the carbon emission reduction effects of these various factors. The results indicated that: (i) per capita residential carbon emissions in China exhibit a slow fluctuating rise followed by accelerated growth, with the sequence of emissions being highest in the eastern region, followed by the northeastern region, western region, and finally the central region; (ii) population size, shared prosperity, urbanization development, and digitalization collectively influence residential carbon emissions in different regions, with population size and consumption structure playing the most significant promoting and inhibiting roles, respectively; (iii) societal development scenarios and low-carbon development scenarios demonstrate a significant advantage in achieving the timely realization of China's overall residential carbon reduction plan.
