Determination of Se(IV), Cd(II) and Pb(II) ions in homeopathic drugs by inversion voltammetry method.

The conditions for identification and quantification of Se(IV), Cd(II) and Pb(II) ions in homeopathic drugs by inversion voltammetry method with the use of EAGRAPH software were established. The studies proved that the method was of high sensitivity in established conditions. The detection limits were 0.

Direct determination of Pb(II) and Cd(II) ions as impurities in some homeopathic drugs by using stripping voltammetry.

The conditions for identification and quantilication of Pb(II) and Cd(II) ions as impurities in homeopathic preparations by stripping voltammetry were established. The tests proved that the method was of high selectivity. The detection limits were 0.
