Аннотация
The chemical durability and radiation resistance of sorbents based on N,N,N′,N′-tetra-n-octyldiglycolamide (TODGA), produced in Russia by impregnating a polymeric support (BAU-1M sorbent) and by introducing TODGA in the step of styrene copolymerization with divinylbenzene (AXIONIT MND 40Т sorbent), were studied. The degree of the extractant washout in nitric acid solutions increases with increasing HNO3 concentration. The amount of TODGA washed out from BAU-1M sorbent is 4–5 times higher than the amount washed out from AXIONIT MND 40Т sorbent. The radiation resistance of AXIONIT MND 40Т TODGA-containing sorbent is relatively low. Upon irradiation to a dose of 2.5 MGy, the capacity of this sorbent decreases by half.
