Objective To investigate and optimize the experiment conditions of determining lead and cadmium with antimony film-plated electrode.Methods Antimony film-plated gold electrode was prepared by in-situ plating for the determination of trace lead and cadmium by differential pulse stripping voltammetry.Results Lead and cadmium displayed well defined peaks in the antimony film-plated electrode by differential pulse stripping voltammetry;and the stripping potential were-0.58 V and-0.81 V for lead and ...
