摘　　要：针对水污染控制中深度除磷难度大的现状,研究利用稀土元素La及Al聚合羟基离子改性膨润土,制备新型高效脱磷吸附剂La/Al复合柱撑粘土(La/Al-PILC),并对该吸附剂进行表征,研究La/Al-PILC吸附剂在不同的研究条件下对水中磷酸根的吸附量和去除率的影响。得出稀土元素改性膨润土对微磷的去除效果较好。The removal of phosphate from wastewater was significant but difficult.This paper researched a new adsorbent for removal phosphate was obtained by pillaring bentonite with La/Al hydroxide polycation,and characterization of La/Al-PILC.At the same time removal efficiency,isotherms and adsorption of La/Al-PILC toward phosphate were researched in different conditions.
