A prototype of an electrochemical multisensor for joint determination of oxygen and Se4 + in liquid media was created. Optimal conditions for measurements (background electrolyte composition, conditions of electroconcentration, working potentials) are determined. The sensitivity of the multisensor to oxygen is (6-9) o 10-8 mol.l-1, the sensitivity to selenium is (2-4) o 10-8 mol.l-1. The method also makes it possible to determine the minimum concentration of Cu2 + 0.8 o 10-8 mol.l-1, and Co2 + - 0.9 o 10-8 mol.l-1.
