Abstract
An equation to describe the migration behavior of organic acids of low molecular weight in capillary zone electrophoresis(CZE) is derived based on the knowledge of the electric chemistry and the theory of acid-base equilibrium. The equation can be readily applied to predicted the migration order for organic acids in CZE. The predictions using the equation agree well with the experiment results by us and other workers. Also, the equation may be used for the estimation of electroosmotic mobility and the calculation of the dissociation constants for acids.Keywords
