Abstract

The sorption of phenolcarboxylic acids in the batch and dynamic modes on MN-200 hypercrosslinked polystyrene was studied. Conditions of the separation of phenolcarboxylic acids by capillary zone electrophoresis were optimized. The time of the analysis of a ten-component mixture including salicylic, 4-hydroxybenzoic, β-resorcylic, protocatechuic, gallic, syringic, caffeic, ferulic, benzoic, and cinnamic acids is no longer than 15 min. A procedure is described for the dynamic group preconcentration of phenolcarboxylic acids on a microcolumn filled with MN-200 and the subsequent determination of individual compounds in the eluate by capillary zone electrophoresis; performance characteristics are presented.
