Sorption new perrhenate anion ion on the diglycidyl benzylamine and polyethyleneimine was studied. The influence of the concentration and pH of model solutions of ammonium perrhenate, and the time of their contact with the ion exchanger at its absorption capacity were observed. It was found that the adsorption capacity of the anion exchanger for removing ions from solution ReO4 − (NH4ReO4) containing 1.02 g/L of rhenium was 373.6 mg of Re/g.
