Rhenium may be separated from V by passing a 0.3N HCl solution containing both ions through a column packed with MMG-1 anion exchange resin (OH form). Washing with O.3N HCl solution elutes the V, and then the Re retained on the resin is eluted with 2.5N NaOH. The separation may also be effected with SBS cationexchange resin (hydrogen form). In this case the Re is eluted with acidified water, and then the V is eluted by washing with a 1:4 NH/sub 3/ solution. For the separation of V from W the solution with a pH 1 is passed through a column packed with anion-exchange Al/sub 2/O/sub 3/. The V is eluted by successive washing with a pH 1 solution containing H/sub 2/O/sub 2/ and then the same solution with no peroxide. The W is then eluted with an ammonia solution. The V and W are determined in the filtrates by the usual methods. For the separation of Re from W the solution, acid to congo paper, is passed through a column of W/sub 2/O/sub 3/. The Re is eluted with HCl, and the W is then eluted with an ammonia solution. The Re and W may be determined in the filtrates. The method for the preparation of the Al/sub 2/O/sub 3/ amion-exchange column is described. (J.S.R.)
