无机离子交换剂的组成与性能研究——（φ′）^1/2函数与IEC关系的探讨

无机离子交换剂的组成与性能研究——（φ′） 1/2 函数与IEC关系的探讨 STUDIES ON INORGANIC ION EXCHANGERS’PROPERTIES AND THEIR CHEMICAL COMPOSITIONS—Approach a relationship between function φ’ 1/2 and IEC 姚兴东 Yao Xindong Liu Liangbin Liu Jinchun Chen Jieke 1 first-author 刘良斌 1 刘锦春 1 程介克 1 武汉大学化学系 武汉大学化学系 Department of Chemistry, Wuhan University Department of Chemistry, Wuhan University 从参数φ′ 1/2 出发,研究了水合金属氧化物、难溶性酸式盐和杂多酸盐的离子交换容量（IEC）与其组成的关系。对于前两者,IEC值与中心离子的φ′ 1/2 值(或平均φ′ 1/2 值)成线性关系。中心离子的价态高、原子量小及强拉电子效应的产生均有利于IEC值的提高。 The relations between the Ion Exchange Capacities（IEC S ） of hydrous metal oxides, insoluble acidic salts or heteropolyaeid salts and their chemical compositions have been investigated with a function ■ in this paper. It shows that the higher valents of central cations with smaller atomic weight would be beneficial for IEC. 无机离子交换剂 交换剂组成与性能关系 inorganic ion exchanger relationship between the compositions of exchangers and their properties 1989-02-01 2021-04-01 2
