Abstract

The reduction of indium(III)-Eriochrome Red B complex is studied in wide ranges of pH and concentrations by cyclic voltammetry with a linear potential sweep. The ratio of components in the complex is found to be 1 : 2. The mechanism of the electrode process is discussed. It is shown that In(III) can be determined in the presence of Cd(II) and Fe(III).
