Popis:	Stripping voltammetry was used to determine bismuth(III) in raw gold ores. The effect of some matrix elements, Cu(II), Au(III), Pt(IV), Pd(II), etc. on the current of bismuth(III) electrooxidation was studied. The conditions the extraction of bismuth(III) dithizonate with chloroform from a complex matrix are found. A procedure is developed for determining bismuth(III) in raw gold ores.
