中文摘要：用溴化十六烷基三甲铵(CTMAB)对蛭石进行改性,并研究了改性蛭石对水中对硝基苯酚的吸附特性.结果表明:改性蛭石的层间距明显变大,对硝基苯酚的去除率可达90%以上;对硝基苯酚的等温吸附曲线符合Langmuir方程;改性蛭石对对硝基苯酚的吸附既有水相与有机相之间的分配过程,又有物理吸附、静电吸附和离子交换吸附等吸附过程;改性蛭石的脱附率为80%.

外文摘要：Organic intercalated vermiculite was synthesized by using cetyltrimethylammonium bromide （CTMAB） and its absorbent characteristics to remove p-nitrophenol from synthetic solutions were analyzed. The results show that the interlayer space of this absorbent becomes larger, its p-nitrophenol removal rate is over 90%, and its adsorption isotherms of p nitrophenol fit to the Langmuir formula; that its adsorption mechanism includes the process of distribution between water phase and organic phase and the integrated process of physical, electrostatic and ion-exchange adsorptions; and that its desorption rate is 80~.
