Kolpakova, L. Gol'ts] The studies on the electropreconcentration of ReO 4 − from 1 M HNO3 solutions have shown that, at −0.8 V, ReO 4 − is reduced to ReO2 and Re0 at the surface of an impregnated graphite electrode. Two anodic peaks were observed in the voltammogram of the electrooxidation of the deposit obtained. The conditions for the adsorption isolation of ReO 4 − on activated carbon from a complex matrix containing Mo(VI), W(VI), Cu(II), Ag(I), and Au(III) were selected. To intensify the adsorption, the solutions are irradiated with UV. A procedure for determining rhenium in mineral ores and naturally occurring samples was proposed.
