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30 min时,百菌清的脱除率可达82%.
以鈉基膨潤土為原料,用十六烷基三甲基溴化銨(CTAB)進行有機改性,製得有機矇脫土.研究瞭有機矇脫土對有機氯農藥百菌清廢水的吸附性能,攷察瞭溶液pH、溫度、吸附時間以及有機矇脫土用量對吸附率的影響.結果錶明:百菌清溶液濃度為0.30 g/L、矇脫土用量為10 g/L、pH為7、溫度25℃、吸附時間為30 min時,百菌清的脫除率可達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.
