摘要:强酸性阳离子交換树脂含有大量的强酸性基团,具有择、交換、吸收和催化等功能,但其存在耐高温
性能差、酸强度低等问题,故需要对其进行改性。改性的阳离子交换树脂广泛应用于水处理、有机合成、分离
处理、环境保护及生物制药等领域。本文简要介绍了近年来强酸性阳离子交换树脂的改性方法,主要包含:金
属离子改性(AHP、Sn4、Zn2、T4、Fe3和Fe2、Ce4和Gia3,N2、Zr4、P2等)、磺化改性、巯基改性、
胺化改性及其他类改性等方法;指出了其存在的问题,分析了改性阳离子交换树脂的未来发展方向,开发和研
制县有耐高热和化学稳定性的树脂裁体材料成为其研究的关键。除此之外,对树脂进行各种改性处理也是改善
树脂综合性能、打大其应用范固的重要方法

Abstract: Strong-acidic cation exchange resin contained a large number of strong acid groups, which
renders it diversed functions of selection, exchange, absorption and catalysis, etc. But the inherent
dcfccts of poor high tcmperature resistancc and low acid strength, makc it obliged to be modified
Modi lied cation exchange resins have been widely used in water treatment, organic synthesis
separation and treatment, environmental protection and biological pharmaceutical, etc, The
modification methods of strong-acid calion exchange resin were reviewed, mainly including: metal 1on
modification(AP、Sn+、Zn2、Ti+、 Feand Fe2、Cet" and Ga3、Ni2、Zf+、Pd2,etc), sulfonation
thiol and amination modification, and othcr modifications, ctc. The prospect of application of modified
cation exchange resins was discussed. The key of the research was to prepare the resin support material
with high heat resistance and chemical stability. In addition, the modification of resin was also an
important method to improve its comprehensive performance and extend its applications
Key words: cation cxchange resin; support; modification; catalysis; adsorption
