摘要
研究了膨润土的改性方法及改性膨润土对水中Cr(Ⅵ)的吸附性能,结果表明,改性膨润土较原土具有更高的离子交换能力和吸附能力,溴化十六烷基三甲铵(CTMAB)改性膨润土综合效果最好,水中残留的CTMAB对处理水未造成二次污染。
A modified method of bentonite is studied in the article as well as the absorption property of the modified to Cr（ Ⅵ ） in water. It concludes that modified bentonite has better property both in absorption and ion-exchanging than. Meanwhile, bentonite modified with CTMAB is supposed to be the best one. At last, we know that remained CTMAB in water doesn＇t lead to second contamination.
