摘　　要：以钠基膨润土为原料,用十六烷基三甲基溴化铵(CTAB)进行有机改性,制得有机蒙脱土.研究了有机蒙脱土对有机氯农药百菌清废水的吸附性能,考察了溶液pH、温度、吸附时间以及有机蒙脱土用量对吸附率的影响.结果表明:百菌清溶液浓度为0.30 g/L、蒙脱土用量为10 g/L、pH为7、温度25℃、吸附时间为30min时,百菌清的脱除率可达82%.Organic bentonite was prepared by using cetyl trimethylammonium bromide （ CTAB） modified sodium bentonite.The adsorption properties of organic bentonite towards organochlorine pesticide chlorothalonil in waste water was investigated including pH values , temperature , adsorption time and amount of organic bentonite .The results showed that the removal rate could reach 82%when 0.30 g/L chlorothalonil solution was absorbed by 10 g/L organic bentonite for 30 minutes at 25 ℃and pH =7.
