摘要/Abstract

摘要： 本文介绍了蛇笼树脂的结构及其离子阻滞作用机理,提出了离子阻滞交换量的概念.研究了残余阴离子交换量、残余阳离子交换量、全阴离子交换量、离子阻滞交换量和全阳离子交换量的测定及计算方法,测定了美国的Retardion11A-8及本文合成的9种蛇笼树脂的交换量.

关键词: 蛇笼树脂, 离子阻滞, 残余离子交换量, 离子阻滞交换量

Abstract: Snake-cage resin is a kind of amphoteric resin with special structure.Because of its unique retardation ability and its advantage of water regeneration it has been used in many ion separation processes.In this article, the author described the structure of snake-cage resin and the mechanism of ion retardation proposed a new concept, ion retardation capacity, to estimate the snake-cage resins.Then the determination of residual anion exchange capacity, residual cation exchange capacity, total anion exchange capacity, ion retardation capacity and total cation exchange capacity were studied.Finally, the determination of these capacities for Retardion 11A-8 and nine other snake-cage resins synthesized by the author was carried out.

Key words: Snake-cage resin, Ion retardation, Residual ion exchange capacities, Ion retardation exchange capacity
