Description
Summary:The effects of monovalent and bivalent impurities on the diffusive mobility sodium, caesium and strontium in magnesium potassium phosphate hexahydrate and clinoptilolite were analysed. It was determined that ratio of diffusion coeffcients of sodium concerning caesium and strontium are in antagonistic dependence on the caesium and strontium content in a matrices on the basis of magnesium potassium phosphate hexahydrate. It is established that the diffusion process in the magnesium potassium phosphate hexahydrate is due to the Frenkel. The influence of the diffusion of impurity elements as a function of the ionic radius and the ion position in the crystal lattice of clinoptilolite has been studied.
