title: Determination of Se(IV), Cd(II) and Pb(II) ions in homeopathic drugs by inversion voltammetry method.
abstract: 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 0.66 microg/mL, 0.08 microg/mL and 0.12 microg/mL for Se(IV), Pb(II) and Cd(II) ions, respectively. This method was characterized by repeatability of measurements, a wide range of linearity and satisfactory percent recovery.
