摘要
用短链季铵盐阳离子表面活性剂四甲基铵离子(TMA)改性膨润土和凹凸棒土,研究它们对模拟地下水中苯系物的吸附作用.二种TMA改性粘土矿物均可以有效地吸附模拟地下水中的苯系物,吸附机理较复杂,主要以表面吸附为主.
Modifying Bentonite and Attapulgite with on short chain quaternary ammonium compound (QAC) tetramethylammonium (TMA) has been done. The sorption of benzene homologues in simulated groundwater by TMA modified clays has been studied. Modified clays have good sorption effect, sorption mechanisms are complex, but surface adsorption is the predominant.
