摘要
Salts of Zinc, Cadmium, Lead and Copper are taken incidentally or accidently and has become of great toxicological importance having toxic effect. In the present study direct determination of Zn, Cd, Pb and Cu metal was carried out from tap water of Delhi (India) using differential pulse anodic stripping Voltammeter (DPASV) at Hanging mercury dropping electrode (HMDE). Determination of Zn, Cd, Pb, Cu was done using Ammonium acetate buffer (pH 4.6) with a sweep rate (scan rate) of 59.5 mV/s and pulse amplitude 50mV by HMDE by standard addition method. The solution was stirred during pre-electrolysis at -1150mV (vs. Ag/AgCl) for 90 seconds and the potential was scanned from -1150V to + 100V (vs.. Ag/AgCl). As a result the minimum level of Zn, Cd, Pb, Cu was Zero and the concentration observed in the tap water sample of Delhi (India) was determined as 0.174 mg/L-1, 0.001 mg/L-1, 0.002 mg/L-1, 0.011 mg/L-1 respectively.
