Abstract

A procedure was developed for determining germanium as a Rhodamine 6G-8-molybdogermanic heteropoly acid ion-pair complex in solutions obtained after germanium separation by solvent extraction from the matrix of various Ge-containing samples. The procedure accuracy was evaluated by determining germanium in a reference standard sample of steel after preliminary separation by solvent extraction. For the certified content equal to 1.1 × 10-4% the found content was 1.1 sx 10-4% (n = 10, RSD = 3.0%, andP = 0.95)
