| 摘 要： | 用阴、阳离子表面活性剂改性制得一系列阴-阳离子有机膨润土,表征了有机膨润土的结构特征,研究了对硝基苯酚在阴-阳离子有机膨润土/水间的界面行为,并探讨了其吸附机理.结果表明:阴-阳离子有机膨润土的层间距和有机碳含量与改性时阴、阳离子表面活性剂的组成和配比有关;阴-阳离子表面活性剂在有机膨润土中形成了增溶(分配)作用较强的有机相,在一定配比下对水中有机污染物产生协同效应.

| Abstract: | A series of anion-cation organobentonites are synthesized by covering anion-cation mixed surfactants on the bentonite. The interlayer spacings and organic carbon contents of anion-cation organobentonites are analyzed. The interfacial behavior of p-nitrophenol betwwen anion-cation organobentonite and water are investigated. The sorption mechanisms are also discussed. The results indicate that the organic carbon contents of anion-cation organobentonites are proportional to the amounts of anion and cation surfactants exchanging onto bentonite. Partition mediums are excellently created in anion-cation organobentonites for organic pollutants in water. Removal rate of organic pollutants from water is improved by synergistic solubilization of anion and cation surfactant on the organobentonites. |
