用Mg（ OH）2乳状液改性天然磷矿粉制成复合型吸附剂．采用分光光度法研究该吸附剂对Cd2＋的吸附性能．考察了复合型吸附剂中磷矿粉与Mg（ OH）2质量比、吸附剂的用量、吸附时间以及溶液pH值对吸附性能的影响．实验结果表明，这四种因素对Cd2＋的吸附均有显著的影响．当吸附剂配比（磷矿粉与Mg（OH）2质量比）为1∶1时，在吸附剂用量为1．0 g/L，吸附时间为1 h，温度为30℃，Cd2＋的初始浓度为0．1 mg/L，溶液为近中性（ pH＝6～7．5）的条件下吸附效果最佳，Cd2＋的去除率可达83．5％．

The compound absorbent was prepared by natural phosphorite and Mg ( OH)2 .It was used to re-move Cd2+from waste water, and the effects of amount proportion , amount of the absorbent, contact time, pH were investigated.The results show that when the amount proportion of Mg (OH)2 and phosphorite is 1∶1, the amount of the absorbent is 1.0 g/L, the contact tine is 1 h and the pH is 6~7.5, the gross removal rate of Cd 2+can reach 83.5%.
