Sorption Recovery of Cesium from High Level Alkaline Waste from Mayak Production Association
The results of the sorption of 137Cs from the clarified phase of accumulated high-level alkaline radioactive waste of the Mayak Production Association with sorbents based on modified nickel ferrocyanide (Fersal) and resorcinol–formaldehyde resin (RFS-I) in batch and flow conditions are presented. In batch mode, the distribution coefficient of 137Cs on Fersal and RFS-I sorbents is 2300 and 730 cm3/g, respectively. In flow mode, the volume of the passed solution before the 137Cs breakthrough for Fersal and RFS-I sorbents is 140 and 85 column volumes, and the maximum purification factor is 104 and 103, respectively. To desorb cesium from the Fersal and the RFS-I, 8 M HNO3 and 1 M HNO3 solutions, respectively, were used. A decrease in the sorption characteristics of the RFS-I sorbent during the sorption of cesium from high-level alkaline radioactive waste was discovered. A conclusion was made about the possibility of using the Fersal sorbent for the recovery of 137Cs from high-level alkaline radioactive waste of the Mayak Production Association.
