Experimental studies of the sorption capacity of the modified double metal oxide MexOy * MnO2, where Me - Ni, Zr, Sn, Al were carried out, distribution coefficients of 137Cs and 90Sr were calculated, ion-exchange sorption and rates of 137Cs and 90Sr were obtained, kinetics of their sorption and selectivity of sorption in pairs Cs-K and Sr-Ca were studied. Established that modification of double oxides by applitcations by the cations of Sr2 + and Cs+ increases the role of ion-exchange mechanisms in the sorption of 90Sr and 137Cs, which will promote the use of modified sorbents in dynamic mode, as well as the regeneration of the sorbent. The principles of a device for sorption-membrane cleaning method and principles of LRW regeneration membranes and sorbents.
