Сonditions of rhenium sorption from sulphuric acid solution by new granular ionite, Levextrel resin and impregnate contained amine or its functional group were determined. To increase the rate of sorption two last materials with mobile phase of extractants were tested. The impregnate contained trioctylamine on macroporous carrier were obtained in the D. Mendeleyev University of Chemical Technology of Russia. Sorption has been carried out in batch and dynamic conditions. Determination of the parameters of rhenium recovery was carried out at varying concentrations of acids and salts, temperature, ratio of sorbent to solution. Equilibrium, kinetic and dynamic characteristics of rhenium sorption were determined.
