摘要

金属离子与不同结构的分析样品之间可产生特异性相互作用，因此金属离子修饰的色谱填料具有特殊的分离选择性。该文以粒径均一、比表面积大、孔径均匀的聚苯乙烯-二乙烯基苯微球为基质，采用浓硫酸对微球中的苯基进行磺化处理，使其被修饰上磺酸基团，具备阳离子交换的功能。并进一步采用离子交换法，将填料上的H

交换成Ag

，制备了具有分离选择性的Ag

修饰聚合物填料。随后将该填料装填成固相萃取（SPE）小柱探讨了其稳定性、使用条件及分离选择性。该文所发展的Ag

修饰聚合物填料具有制备方法简单、稳定性好、对离子吸附能力强等特点，具有良好的分离选择性，装填成SPE柱可满足复杂实际样品预处理的需要。

Abstract

Metal ions may have specific interactions with various analytical samples of different structures，so chromatography stationary phase modified by metal ions usua

lly have specific separation selectivity. In this paper，polystyrene-divinylbenzene microspheres were used with uniform particle size，large specific surface area and uniform pore size. The phenyl groups in the crosslinked microspheres were sulphonated by concentrated sulfuric acid to provide cation exchange function. Furthermore，Ag

modified polymer stationary phase with specific separation selectivity was prepared by exchanging H

with Ag

by using ion exchange method，and were also packed in solid phase extraction（SPE） columns to investigate their stability，running conditions and separation performance. The prepared Ag

modified stationary phase owned the characteristics of simple preparation，good stability，strong ion adsorption ability and good separation selectivity，which could be packed into SPE columns and met the needs of complex practical sample pretreatment with corresponding sample loading and elution methods.
