Research and application of inorganic selective sorbents at Mayak PA

Abstract This work has been performed in order to identify selective inorganic sorbents for caesium and strontium. Thin-layer sorbents with nickel ferrocyanide embedded in an inert matrix were found to be the best for caesium. Sorbents including non-stoichiometric manganese dioxide were selected for strontium. Bench tests have been carried out on the purification of desalted water of SNF storage-pool from 137 Cs, and on the purification of contaminated natural water from 90 Sr. The facility for synthesizing the ferrocyanide sorbent with the registered mark ‘Seleks-CFN’ has been brought into operation. The sorbent ISM-S seems promising for 90 Sr decontamination. To cite this article: M.V. Logunov et al., C. R. Chimie 7 (2004) .
