Abstract
To increase the efficiency of anion exchangers based on copolymers of styrene and divinylbenzene in ion chromatography a new method for spatial separation and hydrophilization of functional groups using epichlorohydrin is suggested. Synthesis consists of acylation of a matrix by acetic anhydride, reductive amination by methylamine hydrochloride, alkylation of the aminated phase using epichlorohydrin, amination by dimethylamine at the terminal chlorine atom, and quaternization of the terminal amino group with epichlorohydrin. The obtained anion exchangers make it possible to simultaneously determine eight anions (F−, HCOO−, Cl−, NO −2 Br−, N −3 HPO 3−4 and SO 2−4 ) and demonstrate high efficiency (more than 62000 N/m for HPO 2−4 ) in a suppressed ion-chromatography mode.
