Original Abstract

This paper describes the preparation and electrochemical application of chromium (III) oxide modified carbon paste electrode for simple and high sensitive simultaneous determination of zinc, cadmium, lead and copper ions. Square wave anodic stripping voltammetry which is very sensitive for metal ions was selected as electrochemical detection method. This method was optimized with respect to deposition time, deposition potential, frequency and amplitude. The detection limits were found to be 30.3 µg/L for Zn2+, 3 µg/L for Cd2+, 24.2 µg/L and 3 µg/L for Pb2+ and Cu2+ respectively. The potential for simultaneous detection of these heavy metal ions by the chromium modified carbon paste electrode was also demonstrated. Using this modified carbon paste is also possible to detect mercury ions, detection limit was found to be 18.2 µg/L
