摘要：

The kinetic studies of exchange of Na+ and K+ on cerium phosphate was studied In alkaline solutions under particle diffusion controle. The effective diffusion coefficient and activation energy have been evaluated. The entropies were calculated and found to be -13.9 and -22.0 J mol(-1) K-1 for Na+ and K+, respectively.
