Abstract

Novel method of synthesis of the anion exchangers based on polysterene-divinylbenzene with cross-linking
degree of 25% is proposed. The method involves acylation of the matrix with w-chloroacylchloride, amination with
primary amines and following alkylation with oxiranes. The approach presented combines the increase of functional
group hydrophilicity and its spatial moving away from the matrix which results in the reduction of the matrix
influence on polarizable ions’ retention. The chromatographic behavior of seven inorganic anions (fluoride, chloride,
nitrite, bromide, nitrate, phosphate and sulphate) on the synthesized sorbents was studied. The obtained anion
exchangers with hydrophilic spatially distant groups demonstrate high efficiency (more than 40000 Tp/m) and good
selectivity of the separation
