| 摘 要： | 用长碳链季铵盐溴化十六烷基三甲胺（ＣＴＭＡＢ）与短碳链阳离子表面活性剂（ＴＭＡＢ）按不同配比改性膨润土。制得一系列双阳离子有机膨润土。研究了双阳离子有机膨润土吸附水中菲的适宜条件、性能及机理，结果表明，双阳离子有机膨润土的层间距、有机碳含晡对菲的吸附性能与改性时表面活性剂的加入量成正相关；菲等温吸附曲线呈线性，是菲在水－双阳离子有机膨润土之间分配作用的结果。

| Abstract: | A series of dual-cation organobentonites are synthesized by replacing the metal ions in bentonite with both cetyltrimethylammonium (CTMA) and tetramethylammonium cation (TMA). The optimal conditions, properties for dual-cation organobentonites to sorb phenanthrene from water are investigated. The interlayer spacing and organic carbons contents of organobentonites, and the sorp-tion of phenanthrene to organobentonites are relative to the amount and akly-length of organic cation exchanging into the bentonite. The sorption of phenanthrene to dual-cation organobentonites is also related to the properties of organic compound. The sorption isotherm of phenanthrene is linear, which is the result of phenanthrene partition into dual-cation organobentonites. |
