摘要：

Equations that describe the electrophoretic migration of monovalent ionic substances in solution with a significant presence of H+ or OH- ions are formulated. A derivation of the Kohlrausch regulating function for these conditions is presented. The model of electromigration consists of a set of continuity equations, together with a set of algebraic equations describing the chemical equilibria involved, and is implemented on a personal computer. Simulation of some experimental phenomena in electrophoretic methods, e.g., the sharpening effect in capillary zone electrophoresis or anomalous spikes in isotachophoretic systems, is presented.
