The diffusion mechanism of alkali metal ions in the particles of cerium(IV) antimonate

The kinetic behaviour of Li +, Na +, K + and Cs + ions exchange on cerium(IV) antimonate were investigated under conditions of particle diffusion and the limited batch technique. Values for the diffusion coefficients, activation energy and entropy of activation were calculated and their significance...
