Here we present a novel approach for uranium removal from aqueous system by chemically modifying low-grade coal (low-carbon and high silicate content) with adenosine 5'-monophosphate (AMP) nucleotide and adsorbent referred here as coal@AMP. Functionalisation of coal was carried out by incorporating amide and phosphate functional groups via oxidation and reduction phenomenon. Chemical make-up and structural morphology of coal@AMP was explored using FT-IR and SEM-EDX analysis. Under the optimised pH 6 and adsorbent dose (10 mg per 100 mL), the coal@AMP exhibited 92.2% removal of uranium from aqueous medium in 300 s, following pseudo-second-order kinetics and Langmuir adsorption isotherm. It corresponded to a maximum adsorption capacity (q<sub>max</sub>) of 624.6 mg/g. The fast and efficient adsorption of uranium by coal@AMP is favoured by the strong interaction or chelation of uranium species with the amide and phosphate groups.

This study developed optimal concrete mixture proportions for different heating and re-curing regimes.

A data set, including approximately 500 mix designs, was collected from the literature to develop an optimal ANN model to predict the first three objectives. The genetic algorithm and particle swarm optimization were used to tune the ANN model's hyperparameters. NSGA-II and MOPSO algorithms, besides this optimal ANN model, were then used to develop the optimal mixture proportions for different heating and re-curing regimes. TOPSIS was utilized to sort the non-dominated solutions and select the optimal one based on different weight vectors. The results showed that the R<sup>2</sup> values for the verification set in predicting the 28-day, residual, and re-cured compressive strengths were 0.999, 0.987, and 0.977, respectively. The sensitivity analysis revealed that the heating regime (especially peak temperature) is the most fundamental input feature in predicting the post-fire behavior of concretes. The optimal concrete mixture proportion depends mainly on the case study, which considers economic, environmental, and post-fire mechanical objectives. Most of the mixtures were high-strength concretes when all objectives were equally weighted. Increasing the cost and embodied CO<sub>2</sub> emissions weights resulted in cost-efficient and environmentally friendly concretes in exchange for inferior mechanical properties. The developed mixtures by NSGA-II were mostly blended with metakaolin when all objectives equally weighted.

Due to the large volume of concrete consumption, there is extensive focus on enhancing its engineering properties without neglecting the sustainability concerns. In the present work, an attempt has been made to produce geopolymer concrete with industrial by-products. Grinding treatment was carried out to improve the reactivity of the as-received/unprocessed pond ash (UPA), and the output was ground pond ash (GPA). A combination of GPA and ground granulated blast furnace slag (GGBS) in the ratio of 70:30 was used as binders in the production of geopolymer concrete (GPC). Furthermore, due to the sustainability factor, UPA was incorporated as a complete replacement for fine aggregate. Sodium hydroxide (NH) and sodium silicate (NS) were used as alkaline activators. In the GPC binder, Na<sub>2</sub>O% and activator modulus (AM), i.e., SiO<sub>2</sub>/Na<sub>2</sub>O, play a vital role in deciding the degree of polymerization. Thus, two binder contents, namely 500 kg/m<sup>3</sup> and 550 kg/m<sup>3</sup>, were used. Two variations of Na<sub>2</sub>O content, namely 5% and 7.5% of binder, have been included. Three AM values-1, 1.5, and 2-were used to prepare concrete samples. Compressive strength and flexural strength of GPC were evaluated. Microstructural properties using scanning electron microscope (SEM), X-ray diffraction (XRD), Fourier transform infrared radiation (FTIR), thermo gravimetric analysis (TGA), and differential thermal analysis (DTA) have been explored in the present study. Cost and embodied energy analysis were also carried out. Strength results indicated that AM of 2 yielded high early strength due to the rapid setting caused by the reaction between GGBS and the readily available higher proportion of SiO<sub>2</sub> in NS. In later stages, it was observed that the AM of 1.5 yielded higher strength because of the synergy in the reaction between GPA and GGBS in combination with alkaline solutions. Furthermore, increased Na<sub>2</sub>O from 5% to 7.5% enhanced the strength by improving the dissolution of aluminosilicates from GPA and GGBS. Among all the combinations, 550, 7.5, 1 mix yielded the highest compressive strength of 42.91 MPa at 28 days. Also, the same combination 550, 7.5, 1, consumed the lowest cost of 205 INR for unit compressive strength production. The combination 500, 5, 1.5 consumed the lowest embodied energy of 40 MJ per unit compressive strength production. However, the results of the mechanical properties, cost analysis, embodied energy analysis, and microstructural studies substantiate that mix with the combination of 550, 7.5, 1 serves as an optimized blend of binder content, Na<sub>2</sub>O, and AM for sustainable production of GPA and GGBS-based GPC.</p>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144339724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 context, lakes also have a negative impact related to the large amounts of water they can consume through evaporation. This paper quantifies the effects of a small artificial lake-Dridu from Romania (with complex usage) on the environment in the context of CC, estimating the blue water footprint (WF) and carbon footprint (CF) under different use scenarios. Thus, an analysis of the evolution of CF and WF is conducted until 2100, considering forecasts of changes in average temperatures, as well as a partial coverage of the lake's surface with floating photovoltaic systems (FPV). During the study period from 2017 to 2021, the average WF was 0.054 million m<sup>3</sup>, and the carbon intensity was 120.23 kg CO<sub>2</sub>e/MWh. By covering 2 ha of the reservoir's surface with FPV, the production and release of CO₂ and CH₄ into the atmosphere decrease, on average, by 30% for WF and 28.13% for CF. For the CC scenarios, it is observed that WF will increase by an average of 10.4%, while the carbon footprint shows no significant variations. It is worth mentioning that this type of approach, e.g., impact of FPV on WF and CF, as well as the use of FPV as a measure of coping with CC, has not been studied yet in any region of Eastern Europe. This study, given that it deals with relatively new technologies (FPV), has some gaps, since the CF is computed based on estimates, not on measured data. However, the results and the methodology currently presented can be used by various stakeholders to identify the best coping mechanism for preserving the water quantity and for generating clean energy. Also, these types of studies can be a good stimulus for the authorities to develop and permit the placement of FPV on small reservoirs and to investigate the effects of such projects in terms of energy, FPV efficiency, water quantity, and quality, as it will allow the actual quantification of different effects and benefits brought by this technology (water quality indicators, GHG emission, reduction of evaporation, FPV energy output).</p>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144332263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}
