In the present communication determination of Zn, Cd, Pb and Cu metals has been carried out from ground water of Hapur District, Uttar Pradesh (India) using differential pulse anodic stripping voltammetry (DPASV) at Hanging Mercury Dropping Electrode (HMDE). Determination of Zn, Cd, Pb and Cu was carried out by using acetate solution as buffer (pH 4.6) with a sweep rate of 0.06 V/sec and pulse amplitude 0.05 V by HMDE by standard addition method. The minimum level of Zn, Cd, Pb and Cu should also be near to zero and the concentration found in the ground water sample of Hapur (India) as analyzed 2.1834, 0.0509, 0.0116 and 0.0331mg/L-1 respectively.

Anodic Stripping

Metals in wine can originate from natural and anthropogenic sources and their concentrations have significant effects on wine proprieties as well in its conservation. In this work, direct and simultaneous determinations of Zn, Cd, Pb and Cu in wine samples were carried out by differential pulse anodic stripping voltammetry without any steps of previous pretreatment. The samples analyzed presented concentration levels from 4.64 to 69.3 µg L−1 of Zn, from 1.74 to 5.25 µg L−1 of Cd, from 4.57 to 17.9 µg L−1 of Pb and from 1.0 to 10.3 µg L−1 of Cu. Accuracy was evaluated with the standard addition method and recoveries ranged from 82.5 and 130.8% for Zn, from 85.7 to 107.0% for Cd, from 89.7 to 101.0% for Pb and from 81.4 to 105.9% for Cu. With the application of this method, it was possible to quantify the metals in a simple and easy way not requiring sample preparation or other approaches for the destruction of organic substances.
