TLDR
In this paper, the determination of lead and cadmium in biological materials was carried out by potentiometric stripping analysis, where the supporting electrolyte was a mixture of NaCl and HCl.Abstract:
The determination of lead and cadmium in biological materials was carried out by potentiometric stripping analysis. Supporting electrolyte was a mixture of NaCl and HCl. In the presence of 4% lumatom in methanol, oxidation potentials of −0.46 V for Pb and −0.68 V for Cd were found (vs. SCE). The method was applied to different standard reference materials (leaves, needles, hair) and was also compared with the differential pulse anodic stripping technique. The latter presented considerable difficulties, in particular by the interference of oxygen.read more
