The diffusion of cobalt chloro complexes in anion-exchange beads has been studied in mixed solvent media. The effects of variables
on the kinetics of the exchange process by the batch technique were examined. The strongly basic anion-exchanger Dowex 2X8
in its Cl− form was used in ethyl alcohol-water-hydrochloric acid solutions. The rate laws were verified experimentally. The dependence
of the exchange rate on the temperature, the viscosity of the solution, the mean resin particle diameter and the composition
of the solution was studied.
