Abstract: Indium and gallium can be simultaneously determined by the thin-film anodic stripping voltammetry at Bi or HgBi thin-film electrode generated in situ on glassy carbon electrode. The Hg TFE is not suitable for determination, namely gallium ions at higher concentrations. From experiments it results that the height of indium peak is strongly influenced by the concentration of gallium ions in analyzed solution. As it was found, indium competes with bismuth and gallium with mercury for surface sites on glassy carbon electrode.
