摘要
对四川三台膨润土进行了提纯 ,分别用十八烷基三甲基铵、十八烷基二甲基苄基氯化铵、十二烷基二甲基氯化铵和十六烷基三甲基溴化氨对膨润土进行了有机化处理 ,并用改性过的膨润土对含铬工业废水进行吸附和解吸实验。同时对比了在相同实验条件下钠化和酸化的吸附结果。结果表明 ,有机化后的膨润土能有效的吸附水中的六价铬离子 ,与其他改性膨润土相比具有更好的吸附效果 ,且不易解吸 。
According to the research results of Sichuan Santai's bentonite that have been purified and undergone organized treatment with separately octadecyl ammonium trimethide, octadecyl dimethyl benzyl ammonium chloride, dihexyl dimethyl ammonium chloride and cetyl trimethy ammonium bromide, and carry out adsorption & adsorbing-free test using the modified bentonite, the effect of adsorbing Cr 6+ in industrial waste water of organized bentonite are more obvious, comparing with those modified bentonite with other methods. So organized bentonite is an effective material to dispose of industrial waste water with Cr 6+ .
