Factors Responsible for the Electrophoretic Behavior of Carboxylic Acid and Triazine Derivatives under Conditions of Capillary Zone Electrophoresis and Micellar Electrokinetic Chromatography

Abstract

The effects of the pH, nature, and ionic strength of the running buffer; temperature; and surfactants, organic solvents, and macrocyclic compounds added to the buffer solution on the electrophoretic separation parameters of anionic, cationic, and neutral components of complex mixtures of organic compounds under the conditions of capillary zone electrophoresis and micellar electrokinetic chromatography. Pesticides from the series of chlorophenoxycarboxylic acids and triazines, as well as amino acids and substituted benzoic acid derivatives, were used as model systems. The predominant role of the addition of macrocyclic reagents, in particular, β-cyclodextrin, as buffer electrolyte components was noted.
