Abstract
In this work, the direct determination of zinc heavy metal in the tap water was carried out by differential pulse anodic stripping voltammetry (DPASV) technique at the glassy carbon electrode (GCE). The zinc ions were deposited by reduction at -1.5 V on a bare glassy carbon surface. Then, the deposited metal was oxidized by scanning the potential of the electrode surface from -1.5 to -0.8 volt using a differential puls mode. The stripping current arising from the oxidation of metal was connected with the concentration the metal in the sample. The concentration of zinc heavy metal found in tap water sample was determined to be 180 mu g L(-1) using 0.2 mol L(-1) acetate buffer (pH: 3.50).
