FIELD: organic electrochemistry. SUBSTANCE: concentration of hydrogen sulfide in analyzed object is determined by calibration graph-linear dependence of concentration on value of anode peak of cation-radical of hydrogen sulfide by current which was obtained with use of method of cyclic volt-amperometry. Construction of calibration curve is based on ability of hydrogen sulfide to electrochemical single-electron oxidation in non-aqueous media to cation-radical with potential Ena=1.7 V. EFFECT: raised accuracy of determination of concentration of hydrogen sulfide and decreased time of analysis. 1 cl
