“…Solvent extraction is an option for 137 Cs removal, but this technique has several shortcomings, e.g. extraction coefficients for cesium are relatively small and process needs huge volumes of solvents and stripping agents [ 1 , 2 ]. Precipitation has been applied in few works, however, the higher pH values typically associated with precipitation methods often result in the precipitation of macro quantities of metals necessitating further separation or decontamination process steps [ 3 ].…”

Dynamic adsorption of radiocesium on titanium ferrocyanide grains from reactor coolant simulating solution containing salts at moderate concentrations has been investigated. Effective decontamination of the neutral solutions has been achieved, in the amounts of a more than 20 thousand bed volumes. After adsorption the titanium ferrocyanide was transferred to titanates and calcined at 900 °C. The leaching test of the obtained lithium titanates indicates that the loaded adsorbent can serve as an effective primary barrier in nuclear waste repositories.
