The sample is subjected to repeated filtration through the sorbent remotely in the circulation mode with the return of the filtrate back to the container. During the filtration process, the concentration of activated corrosion products from the sample is controlled by measuring the residual activity of these products in the filtrate after their isolation on the sorbent after a certain period of time. Filtration is completed under the condition that at least 98% of radionuclides of activated corrosion products are isolated, and a sorbent modified with antimony crystalline acid is used as a sorbent.
