Abstract  

Sorption and diffusion processes with134Cs and85Sr in natural bentonites have been investigated. The distribution coefficients (K d ) have been determined by a batch method. Various factors affecting theK d value as water-to-bentonite ratio, concentration of the competitive cations in the aqueous phase or bentonite-to-sand ratio in the mixed sorbents have been evaluated. A comparison of the sorption and diffusion data has been made.

Abstract  

Retardation mechanisms of134Cs and85Sr have been investigated. Batch determination of distribution coefficientK d have been carried out for various values of factors affecting retardation such as solid-liquid ratio, particle size, composition of solid phase. Various types of bentonites and mixtures of bentonites with sand have been also studied.
