Various types of carbon-containing sensors (electrodes) — glassy carbon, impregnated graphite, thick-film graphite and modified sensors — and two versions of stripping voltammetry — differential pulse voltammetry and fast linear scan response differentiation voltammetry — are described. By way of example, concentrations of Cu, Pb and Cd were determined with in situ mercury plated electrode, those of Pb and Cd on modified electrodes in the absence of metallic mercury or soluble mercury salts, and those of Cr, W and Ni using adsorptive stripping voltammetry. The fast linear scan response differentiation voltammetry is shown to have certain advantages, such as elimination of the need for removal of oxygen from the solution and well defined responses of reversible and quasireversible processes, specifically, from copper.
