The measurement of the chemical reaction rates for complex formation as well as hydrolysis type reactions by the method of horizontal zone electrophoresis is outlined. The correlation between chemical equilibrium kinetics and electrodiffusion processes in a constant d.c. electric field is described. In model electromigration experiments the reaction rate constant of the formation a complex by Hf(IV) and diethylenetriaminepentaacetic acid (DTPA) is determined. The electrophoretic mobility, diffusion coefficient and stability constant of the [HfDTPA]- complex are calculated, taking into account experimental electrophoretic data obtained at 298.15±0.05K and constant ionic strength. No-carrier-added 175Hf radionuclide was used in electromigration experiments at concentrations of 10-10-10-11M.
