摘要

通过在膨润土上添加烷基铵阳离子和有机螯合剂，合成了十六烷基三甲基溴化铵-二乙烯三胺五乙酸-膨润土。研究了ctmab - dtpa -膨润土对有机污染物(苯酚)和重金属(Cu2+、Cd2+)混合污染物的同时吸附性能。ctmab - dtpa -膨润土对水溶液中的混合污染物有明显的吸附作用。将Langmuir和Freundlich等温线方程应用于数据，并对等温线方程的参数值进行了计算。

The performance of the CTMAB-DTPA modified bentonite as a sorbent for Cu2+, Cd2+ and phenol

CTMAB-DTPA-bentonite (hexadecyl trimethyl ammonium bromide-diethylene triamine pentaacetic acid-bentonite) was synthesized by placing alkylammonium cation and organic chelating agents onto bentonite. The simultaneous adsorption of organic pollutant (phenol) and heavy metals (Cu2+ and Cd2+) mixed contaminant on CTMAB-DTPA-bentonite was investigated. The CTMAB-DTPA-bentonite showed significant adsorption for the mixed contaminant from aqueouss solution. The Langmuir and Freundlich isotherm equations were applied to the data and values of parameters of these isotherm equations were evaluated.
