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.
Bentonite and attapulgite were modified with tetrabutylammonium (TMA), a short-chain quaternary ammonium salt cationic surfactant, to study the adsorption of benzenes in simulated groundwater. Both TMA-modified clay minerals were effective Adsorption of simulated benzene in the groundwater, adsorption mechanism is more complicated, mainly surface adsorption.
