Abstract

New anion exchangers for ion chromatography were obtained as a result of the synthesis
including acetylation of styrene-divinylbenzene copolymer, containing 25% of divinylbenzene, reductive
amination of carbonyl groups and following alkylation. The structure of functional groups was varied
using different alkylating agents. By means of suppressed ion chromatography with conductometric
detection the behavior of seven inorganic anions, namely, fluoride, chloride, nitirite, nitrate, bromide,
phosphate and sulphate were studied on obtained anion exchangers. Anion exchangers alkylated with
epoxides are characterized with higher efficiency and have less influence of polystyrene-divinylbenzene
matrix on the retention of polarizable ions of nitrate and bromide
