The problem of overlapping peaks of antimony and copper, as well as lead and tin, was solved by performing differential pulse anodic stripping voltammetry and differential pulse voltammetry in a 1.8 M HCl–80% isopropanol supporting electrolyte media. Arsenic ( III ) does not interfere in the alcoholic medium and it can be determined by differential pulse voltammetry in acidic aqueous solution. The procedure has been applied to the determination of trace metals in alloy steel.
