| 摘 要： | 在实验室条件下制备了水铁矿和水铁矿与腐殖酸复合物，通过X射线衍射、傅里叶红外光谱、Zeta电位及比表面积的测定对其基本性质进行了表征，并采用静态批处理吸附试验研究了水铁矿及其腐殖酸复合物对Sb（V）的吸附行为特征，探讨了吸附时间、初始pH值、初始浓度、不同干扰离子（PO43-、CO32-、NO3-和Cl-）对水铁矿及其复合物吸附Sb（V）的影响.结果表明：腐殖酸与水铁矿结合后未改变水铁矿的晶型结构，但降低了水铁矿的零电点与比表面积.水铁矿及其复合物对Sb（V）的吸附过程符合Langmuir和伪二级动力学模型，腐殖酸的加入抑制了水铁矿对Sb（V）的吸附.随着pH的上升，水铁矿与复合物的去质子化能力增强，对Sb（V）的吸附量减小；溶液中共存离子PO43-、CO32-对水铁矿及其腐殖酸复合物吸附Sb（V）有较强的抑制作用.
