Americium sorption by crown-ether-impregnated polymeric sorbents from nitric acid solutions and multicomponent nitrate solutions that model process solutions was studied. Sorption of ballast elements by the unimpregnated Porolas-T support was studied. The sorption coefficients K(d) of these elements on Porolas-T do not exceed 0.01. Sorption of the same elements by crown-ether-impregnated sorbents was also studied. Dicyclohexano-18-crown-6 (DCH18C6) and its alkyl derivatives were used. Sorption coefficients were determined for all ballast elements. At the final stage of the study, (241)Am sorption coefficients of from multi - component solutions were determined. The data obtained signify the utility of crown-ether-impregnated sorbents for recovering (241)Am from multicomponent technological solutions. DOI: 10.1134/S0036023611070217
