摘　　要：采用阴离子表面活性剂十二烷基硫酸钠(SDS)研究了胶团强化超滤法处理含Cd^(2+)废水,考察了SDS浓度、Cd^(2+)浓度、pH值、温度对去除率的影响。结果表明,当SDS浓度为1.0cmc,Cd^(2+)浓度为50mg L^(-1)时,去除效果最好,Cd^(2+)的去除率可达到为98.4%。pH对Cd^(2+)的去除影响较大,Cd^(2+)的去除率随着pH的上升增加明显。随着温度的上升,Cd^(2+)的去除率都有所下降。Removal of Cd^2＋ from wastewater by micelle-enhanced ultrafiltration using surfactant sodium dodecyl sulfate（SDS） was investigated. The effects of SDS Cd^2＋ concentration, pH values and temperature on rejection were studied. When the concentration of SDS was 1.0 cmc, the concentration of Cd^2＋ was 50 mg L^-1, the best rejection was 98.4%. Effect of pH value on Cd^2＋ rejection was obvious, rejection of Cd^2＋ increased sharply with the increase of pH value. Rejection of Cd^2＋ decreased with the temperature increasing.
