С. 277-279Abstract: In this work, we propose a method for creating an electrode modified with chromotropic acid for determining the chromium (VI) content in various objects by stripping voltammetry. A possible mechanism for the formation of an electroactive coating capable of adsorption concentration of chromium on the electrode surface is proposed. The optimal conditions for the determination of chromium in the concentration range of 10-6 ÷ 10-9 mol/dm3 have been selected. The approbation of the electrode was carried out on model systems of natural and technological waters.
