[en] Simultaneous electrolytic deposition is proposed for minimization of Cu²⁺ and Pb²⁺ interferences on automated determination of Cd²⁺ by the Malachite Green-iodide reaction. During electrolysis of sample in a cell with two Pt electrodes and a medium adjusted to 5% (v/v) HNO₃ + 0.1% (v/v) H₂SO₄ + 0.5 mol L^-1 NaCl, Cu²⁺ is deposited as Cu on the cathode, Pb²⁺ is deposited as PbO₂ on the anode while Cd²⁺ is kept in solution. With 60 s electrolysis time and 0.25 A current, Pb²⁺ and Cu²⁺ levels up to 50 and 250 mg L^-1 respectively, can be tolerated without interference. With on-line extraction of Cd²⁺ in anionic resin mini column, calibration graph in the 5.00 - 50.0 μg Cd L^-1 range is obtained, corresponding to twenty measurements per hour, 0.7 mg Malachite Green and 500 mg Kl and 5 mL sample consumed per determination. Results of the determination of Cd in certified reference materials, vegetables and tap water were in agreement with certified values and with those obtained by GFAAS at 95% confidence level. The detection limit is 0.23 μg Cd L-1 and the RSD for typical samples containing 13.0 μg Cd L^-1 was 3.85 % (n= 12). (author)
