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.
