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 …
