Zinc, cadmium, lead, copper, thallium, nickel, and cobalt by voltammetry
Zn, Cd, Pb, Cu, Tl, Ni, and Co must be determined regularly in all types of water samples. Zn, Cd, Pb, Cu, and Tl are determined on the HMDE by anodic stripping voltammetry (ASV), Ni and Co by adsorptive stripping voltammetry (AdSV).
