The mechanism of diffusion and ionic transport of alkali metal ions in the particles of tin (IV) antimonate

The kinetics of exchange of Li +, Na +, K + and Cs + ions on tin (IV) antimonate with H + form was studied particle-diffusion-control conditions at different temperatures. The values of activation energy, diffusion coefficient and entropy of activation increase with the ionic mobilities and radii, a...

Summary:The kinetics of exchange of Li +, Na +, K + and Cs + ions on tin (IV) antimonate with H + form was studied particle-diffusion-control conditions at different temperatures. The values of activation energy, diffusion coefficient and entropy of activation increase with the ionic mobilities and radii, and decrease with the hydration energy of the alkali metal ions. On the basis of the kinetic parameters, the exchange of alkali metal ions occurs in the unhydrated form.
