1. A method of differential pulse anodic stripping voltammetry comprising the steps offilling a solution containing ions of a metal to be analyzed into an electrolytic cell having a working electrode and a counter electrode,applying a plating voltage across the counter electrode and the working electrode to plate the same with the metal,applying across the counter electrode and the working electrode a DC stripping voltage having superimposed thereon a pulse voltage having a repetition period of 16.7 to 400 milliseconds in order to strip the metal that has been plated on the working electrode by the plating voltage,measuring a first sampling current which flows through the working electrode during a predetermined interval in which the pulse voltage is not applied,measuring a second sampling current which flows through the working electrode while the pulse voltage is applied, anddetermining the difference between the first and second sampling currents.
