文摘
Novel PS-DVB-based anion exchangers with carboxyl functionalities in ion-exchange layers. Use of glycine as a primary amine for the formation of hyperbranched functional layers. Selectivity variations with changing the location and number of carboxyl groups in the layer. Good selectivity toward weakly retained organic acids and oxyhalides. Possibility of separating 22 anions on 25-cm column within 60 min in gradient mode.
