| 摘 要： | 利用活性炭制备了水合氧化铁负载活性炭AC-Fe，并通过静态吸附实验研究了该材料对水溶液中草甘膦的吸附性能。研究结果表明，该负载方法可以在活性炭上嫁接72 mg/g的铁，AC-Fe对草甘膦的最大吸附容量可以达到120 mg/g；AC-Fe对草甘膦的吸附量随pH的升高而降低；磷酸根对AC-Fe的吸附性能具有明显的抑制作用，原因在于它能和铁离子形成内层络合物，与草甘膦竞争材料表面的吸附位点。

| Abstract: | Hydrous ferric oxide was preloaded into an activated carbon, and glyphosate adsorption properties by this material were studied through batch tests. Results showed that 72 mg/g Fe was grafted onto AC, and the Qmax was increased to 120 mg/g. Adsorption of glyphosate by AC-Fe decreases with increasing pH. The existence of phosphate decreased glyphosate adsorption significantly because of its complexation with actived binding sites on hydrous ferric oxide. |
