The mechanisms controlling the sorption of compounds on organoclays are dependent on the type of organic cations forming organoclays. We used quaternary ammoniumcations of the general form [(CH3)3NR]+,where R is an aromatic or alkyl hydrocarbon group, to replace inorganic cations on clays. When R is a relatively small group (e.g., R=−CH3, −C6H5) the organic cations in the interlamellar region of the clays
are isolated from each other. Such organoclays have relatively high surface areas and display characteristics of surface adsorbents. Alternatively, when R is a large alkyl group [e.g., hexadecyltrimethylammonium (HDTMA), R=−C16H33], the resultant organoclays have low surface areas and act as partitioning media in the sorption14−16.

控制在 organoclays 上的化合物的 sorption 的机制依赖有机阳离子的类型形成 organoclays 。 我们用了一般的形式四个一组 ammoniumcations[(CH3)3 NR]+, R 在哪里一芬芳的或烃基碳化氢团体, 代替在泥土上的无机阳离子。 当 R 是一个相对小的团体时候 (举例来说,R=?CH3,?C6H5) 在泥土的瓣间区域中的有机阳离子
与彼此分开。 如此的 organoclays 相对地有高的表面区域并且显示表面 adsorbents 的特性。 二者择一地, 当 R 是一个大的烃基团体的时候 [举例来说, hexadecyltrimethylammonium(HDTMA),R=?C16H33],合量 organoclays 让低点升至水面区域并且担任区分 sorption14 的媒体?16
抱歉啊,只能是这个水平拉*****
