Abstract

A set of new sorbent were obtained by impregnation different amounts of endoreceptor dibenzo-18-crown-6 in the styrene–divinylbenzene polymer matrix “Porolas-T”. Physical and chemical parameters of strontium sorption on a natural mixture of isotopes from nitric acid solutions were investigated, namely isotherm of sorption, dependence of the distribution coefficient on the concentration of nitric acid in a solution and concentration of crown ether in the sorbent, kinetics of sorption and desorption of strontium. The selectivity of strontium sorption was studied to the alkaline, alkaline-earth metals and cobalt. The sorption properties of sorbent were examined to extraction of radioactive 90Sr.
