Abstract
The kinetics and mechanism of diffusion of Cs+, Co2+ and Eu3+ in the H+-form of silico(IV)titanate (SiTi) have been studied. The sorption conditions were set to study the particle diffusion mechanism only and is confirmed from straight lines of Bt versus 1/r2 plots. The values of diffusion coefficients, activation energy and entropy of activation were calculated and their significance was discussed. The data obtained have been compared with that reported for other organic and inorganic exchangers.
