The physicochemical properties of MSP were characterized via XRD, FTIR, FESEM-EDX, and pHpzc analysis. The biosorption process was optimized using the Box-Behnken design (RSM-BBD), to evaluate the influence of MSP dose (0.02-0.1 g/100 mL), contact time (20-300 min), and solution pH (4-10). The desirability function further refined and validated the BBD results, demonstrating that maximum MB removal (98.7%) was achieved at an MSP dose of 0.09 g/100 mL, contact time of 276.1 min, and solution pH of 8.7. Kinetic modeling indicated that MB biosorption onto MSP conformed to the pseudo-second order (PSO) model. The intraparticle diffusion (IPD) model supports a multi-step adsorption process, consisting of surface adsorption, gradual diffusion, and equilibrium stages. The adsorption equilibrium data were well described by the Langmuir and Freundlich isotherm models, confirming a combination of monolayer and multilayer adsorption profiles. The maximum adsorption capacity (qmax) of MSP was estimated to be 128.3 mg/g. The biosorption mechanism was attributed to hydrogen bonding, π-π interactions, electrostatic forces, and pore filling, as evidenced by spectroscopy and bioadsorbent morphology results. The reusability study demonstrated that MSP retained significant adsorption capacity over multiple cycles, highlighting its moderate recyclability. These findings establish MSP as a highly efficient, scalable, and environmentally sustainable bioadsorbent for MB dye removal, offering a practical solution for wastewater treatment applications and options for sustainable water management.","PeriodicalId":14235,"journal":{"name":"International Journal of Phytoremediation","volume":" ","pages":"1-16"},"PeriodicalIF":3.4,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144012020","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 impacts of exogenous Si application on root morphology, enzymatic activities, proline and glycine betaine (GB) accumulation, reactive oxygen species (ROS), and other physiological parameters of cabbage plants grown under Ni stress were observed.

The overall findings suggest that foliar application of 2 mM Si can enhance root morphology, regulate nutrient uptake, and play a crucial role in reducing Ni accumulation.

The prepared nanocomposites (CuNi/PEI) were characterized using several analytical techniques including Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction analysis (XRD), scanning electron microscope (SEM), and thermogravimetric analysis (TGA). FT-IR showed that several phyto-constituents could act as reducing and stabilizing agents for CuNi. Some nanoparticles looked spherical and some others were nano-rods. The XRD sharp peak, at 2θ = 25.4°, indicated the crystalline nature of CuNi bimetallic nanoparticles. The crystallinity of CuNi was not significantly affected after surface functionalization with polyethyleneimine. The prepared nanocomposites were thermally less stable than CuNi. Further, the nanocomposites were used for the adsorption of two anionic dyes namely Acid Blue 25 (AB25) and Naphthol blue black B (NBBB). At optimum conditions, the highest adsorption capacities of AB25 and NBBB using CuNi/PEI nanocomposites were 198 and 152 mg/g, respectively. However, the adsorption abilities of AB25 and NBBB using CuNi bimetallic nanoparticles were only 35 and 24 mg/g, respectively. The adsorption mechanism was exothermic, nonspontaneous, and fitted well to the pseudo-second order kinetic model and Langmuir isotherm.

The results demonstrated that the incorporation of 5% effectively modulated the pH of acidic soil, substantially elevating soil organic matter, and available N, P, K content. Moreover, it augmented the activities of catalase, urease, and acid phosphatase in the soil, concurrently diminishing the Cd content. This treatment reduced the exchangeable and carbonate-bound Cd fractions by 45% while enhancing the iron-manganese oxide-bound, organic matter-bound, and residual Cd fractions by 26%, 29%, and 96%, respectively. Regarding the growth of pakchoi, the 5% biochar application significantly decreased the Cd content in the edible portion by 51%. It significantly enhanced the fresh weight per plant, soluble solids, soluble sugar, soluble protein, and vitamin C content of pakchoi. In conclusion, the application of T. grandis peel biochar is a viable approach for improving the properties of Cd-contaminated soil, passivating Cd fractions, and enhancing the yield and quality of pakchoi.

This study aimed to evaluate their potential in mitigating heavy metal contamination in soil and plants. Our results shows that SZ and NBC treatments significantly impacted heavy metal levels, notably reducing arsenic (As), nickel (Ni), lead (Pb), cadmium (Cd), and mercury (Hg) accumulation in plant tissues. The treatments exhibited varying degrees of effectiveness in reducing heavy metal levels. Notably, SZ2 treatment decreased As and Pb levels by 33.33% and 20%, respectively, while NBC3 achieved even greater reductions, lowering As by 53.33% and Pb by 30%. Moreover, SZ2, SZ5, and NBC3 treatments halved Cd levels, showcasing their potential in mitigating heavy metal contamination in rice. However Hg levels remained largely unaffected, except for NBC1, which unexpectedly doubled its concentration. In soil, SZ2 treatment significantly reduced metal concentrations, particularly Cd (66.8% reduction) and Hg (70.7% reduction). Conversely, SZ3 and SZ7 treatments increased metal concentrations, suggesting that certain zeolite applications might enhance metal bioavailability. NBC treatments showed varying effectiveness, with NBC3 being the most effective, substantially reducing As, Pb, and Cd levels.","PeriodicalId":14235,"journal":{"name":"International Journal of Phytoremediation","volume":" ","pages":"606-623"},"PeriodicalIF":3.4,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142695476","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}
