Non-wood-based biochars as promising and eco-friendly adsorbents for chromium hexavalent Cr (VI) removal from aquatic systems: state-of-the-art, limitations, and potential future directions

Environmental Pollutants and Bioavailability, Год журнала: 2024, Номер 36(1)

Опубликована: Авг. 14, 2024

Chromium exists from both natural geological processes and human actions, it has a substantial impact on health ecosystems. This study addresses the major challenges in using biochar as an environmentally friendly, sustainable, economical sorbent for removing chromium hexavalent throughout remediation process. The results exhibited that produced non-woody feedstocks pyrolyzed at (300°C −700°C) significantly large amount of various functional groups, higher pH (7 to 11.10) CEC (27 21.70 cmol kg−1), greater surface area (2–300 m2g−1), O/C H/C ratios with increasing carbonization temperature, adsorption capacities (1.63 435 mg g) superior performance removal compared biochars woody-biomass. use equilibrium isotherm, thermodynamic, kinetic models aids comprehending interactions between biochar, well their processes.

Hydroxyl radicals (·OH) are prevalent in diverse ecosystems, including aquatic, atmospheric, and biological environments, crucial the regulation of carbon nitrogen cycles. However, there is still a lack an easily applicable, efficient, precise quantitative structure–activity relationship (QSAR) model for determining second-order reaction rate constants between ·OH pollutants. Herein, QSAR was constructed utilizing molecular images vision transformer conjunction with density functional theory (DFT) to efficiently precisely forecast involving hydroxyl The exhibits strong resilience predictive precision achieved through transfer learning fine-tuning, yielding test root-mean-square error values within range 0.2616–0.3239, surpassing performance image-convolutional neural network model. sites were accurately identified high level precision, as evidenced by F1-scores (>0.9775) AUC-ROC (>0.9665), along validation using gradient-weighted class activation mapping Fukui function based on DFT. This research offers cost-effective alternative complex experimental methods introduces novel tool environmental monitoring risk assessment, highlighting its significance practical utility.
