Transition Metal Ion

Ion-exchange rate curves of aqueous and ammonia transition metal ion complexes are presented together with ion-exchange isotherms of the corresponding complexes using molecular sieves as ion-exchangers. The data are treated mathematically according to Danes and Wolf procedure and the diffusion coefficients for the specific transition metal ion complexes are obtained. Finally, the variation of diffusion coefficients with the extent of ion exchange is followed.
