Zusammenfassung:A method using inversion voltammetric determination of the content of chromium released into model media from houseware has been developed. The optimum conditions for analysing chromium content were established: the background electrolyte - HNO3 of concentration 0.4 M, accumulation of chromate ions on the surface of C/Ag electrode under potential of +200 mV for 60-80 s, registration of the voltammetric curve from +200 to -350 mV at the potential sweep rate of 600 mV/s. 4 refs.
