| 摘 要： | 研究了用溴化十六烷基三甲胺(CTMAB)改性的膨润土处理甲基对硫磷废水的主要影响因素。结果表明:用过150目筛含CTMAB1.5%的改性膨润土15g/L,在pH为7、振荡吸附40min的条件下,对40mg/L的甲基对硫磷的去除率大于95%,剩余的甲基对硫磷的浓度小于2mg/L。

| Abstract: | This article researchs the major factors influencing on disposing parathionmethyl wastewater by CTMAB modified bentonite.The result shows that,under the conditions: the usage of CTMAB modified bentonite passin g sieve 150 is 15g/L,pH value is 7,mixing adsorbing time is 40 min,the removi ng rate of parathionmethyl is above 9.5%,and the rest parathionmethyl is less than 2mg/L in the waste water. |
