Polyalkyl methacrylate monolithic columns for ion chromatography

Abstract

The polyalkyl methacrylate monolithic anion-exchangers with cross-linking degree 26% and ion capacity in range 0,01-0,52 meqv/g were obtained. The dimethylaminoethyl methacrylate and the trimethylamine as the amination agents were used. The influence of modification conditions and composition of polymeric mixture was studied. The procedure of direct obtaining of anion-exchange monolithic sorbent based on ternary amino-copolymer by using thermo-initiated free-radical polymerization and the procedure of amination of polyalkyl methacrylate support were compared. The selectivity and the efficiency of separation of anions using prepared anion-exchangers were studied by ion chromatography with conductometer detector.
