Abstract
The problem of overlapping peaks of antimony and copper, as well as le ad and tin, was solved by performing differential pulse anodic strippi ng voltammetry and differential pulse voltammetry in a 1.8 M HCl-80% i sopropanol supporting electrolyte media. Arsenic (III) does not interf ere in the alcoholic medium and it can be determined by differential p ulse voltammetry in acidic aqueous solution. The procedure has been ap plied to the determination of trace metals in alloy steel.
