In spite of selectivity of platinum and rhenium stripping voltammetry analysis techniques, it is very difficult to identify them in the presence of other metals. This manuscript reports on the stripping voltammetric determination of platinum and rhenium in the presence of other metals. The effect of accompanying elements on the electrochemical oxidation processes of platinum and rhenium has been described. It has been shown that it is possible voltammetric determination of platinum and rhenium after removal of interfering matrix components of mineral raw materials at the stage of sample preparation.
