The polarographic behavtor ot indium in the presence of trihydroxyglutaric acid in acid, nautral, and alkalino media was studied. The vaIue of the half-wave potental of a simple indium ion was determined in HClO/sub 4/ by the half-peak: potential during the anodic dissolutaon of and indium from an amalgam. The half-wave potential is eqia; tp 0.488 v. The effect of the concentration of trihydroxyglutaric acido on the E/sub 1/2/ of indium was studied. It was found that the regular shift of E/sub 1/2/ on changing the concentration of trihydroxyglutaric acid is observed only at pH 4 and pH ll. The coordination number p = 2 and the unstability constant for the indium-trihydroxyglutaric aeid eonnplex at pH 4 were found. K (mean) is (9.73 plus or minus 0.82) x 10/sup - 11/. It was established that the process of indium reduction at pH 11 is irreversible. A method was suggested for the polarographic determination of indium and cadmium, when present together, in trihydroxyglutaric acid at pH 3 and pH 9. (auth)
