摘要: 本研究通过化学改性手段，系统探讨了花生壳生物炭对水体中二氯喹啉酸(QNC)的吸附特性及其作用机制。改性后的生物炭在比表面积和孔隙结构上得到了显著改善，表面官能团的数量也有所增加，从而大幅提升了其对QNC的吸附效果。吸附等温线实验表明，Freundlich模型可有效刻画吸附行为，表明该过程涉及多层吸附。研究发现，pH值对生物炭的吸附性能有显著影响，吸附过程主要通过静电作用和表面络合实现。本研究为改性花生壳生物炭去除水体中的QNC的应用提供了理论基础，展示了其在污染治理中的潜在应用前景。
Abstract: This study systematically investigated the adsorption characteristics and mechanisms of peanut shell biochar for quinclorac (QNC) in water through chemical modification. The modified biochar exhibited significant improvements in specific surface area and pore structure, as well as an increase in the number of surface functional groups, thereby greatly enhancing its adsorption capacity for QNC. Adsorption isotherm experiments indicated that the Freundlich model effectively described the adsorption behavior, suggesting that the process involves multilayer adsorption. It was found that pH significantly affects the adsorption performance of biochar, with the adsorption process primarily driven by electrostatic interactions and surface complexation. This study provides a theoretical basis for the application of modified peanut shell biochar in removing QNC from water and demonstrates its potential for pollution control.
