找不到啊!

阳离子交换容量的单位

这个是属于高等化学的专业知识,我也不懂,帮你找了下,好象是一种什么单位,我把相关资料发给你,你自己看,分数不重要

三聚氯氢酸二甲基乙基四级铵盐离子层析剂之单管柱离子层析法研究

作者/杨永华(国立台湾师范大学化学系)

摘要

本研究以微粒矽胶为基质,运用矽烷耦合剂与其进行修饰反应,再与含三聚氯氢酸四级铵盐反应,制备成以矽胶为基质的阴离子交换剂,经由浆式填充后,以单管柱离子层析法进行研究。
经由元素分析测定离子交换容量,探讨其对一些无机和有机阴离子的层析行为,包括探讨一系列直链有机双质子酸为冲提剂时的浓度效应,冲提剂对阴离子的选择性,冲提剂pH值对阴离子滞留的影响并以不同的颗粒大小矽胶基质填充管柱,探讨其层析行为的差异。
研究结果显示:含三聚氯氢酸四级铵盐阴离子交换剂的层析行为受到冲提剂浓度的影响,阴离子的调整滞留时间随冲提剂浓度的增大而降低,并随离子交换容量而变化。碳链较短的有机双质子酸冲提剂表现离子换机制,碳链较长的冲提剂则包含吸附与疏水性交互作用这些冲提剂中的单价与二价阴离子的成分莫耳分率组成决定其离子强度并影响层析行为。5μm与10μm矽胶层析行为的差异为解析度与基线平整。

Abstract

Several silica-based anion exchangers for single-column ion chromatography (SCIC) were prepared by immobilizing quaternary am-monium salts of cyanuric chloride onto the surface of silane-modified silica-gel. Some stationary phases of low capacities (0.06-0.16 mequiv./g ) were obtained and effective separation of monovalent anions was achived with a series of homologous dicarboxylic acids as eluents on short columns using a conductometric detector.
Factors that can affect the retention behavior, such as eluent species, eluent concentration and eluent pH, capacity of anion exchanger were examined. The results demonstrate that the retention of anions is governed by ion-exchange, adsorption and hydrophobic interactions.
