摘要

用有机螯合剂二乙基二硫代氨基甲酸钠(DDTC)对天然钠基膨润土进行改性，制备了一种去除混合污染物(Cu2+、Cd2+和苯酚)的新型吸附剂(DDTC-膨润土)。研究了ddtc -膨润土的最佳制备条件。此外，ddtc -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。

Preparation of organic chelating agents modified bentonite for mixed contaminant removal from aqueous solutions

Natural Na-bentonites were modified with an organic chelating agent, sodium diethyldithiocarbamatre (DDTC), to prepare a new adsorbent (DDTC-bentonite) for mixed contaminant (Cu2+, Cd2+ and phenol) removal. The optimal conditions for preparation the DDTC-bentonite were investigated. Moreover, the DDTC-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.
