Abstract
This work deals with antimony-impregnated activated carbon electrode for the detection of heavy metal ions. Activated carbon is employed to enhance the surface area of the working electrode. Square-wave Anodic Stripping Voltammetry is performed to analyze the electrolytic solution. The peak currents for cadmium and lead are 29.2 and 49.44 mu A respectively, in 100 mu g/L of cadmium and lead solution, which are considerably higher when equated with the previous reported values. Results also indicate that antimony-impregnated activated carbon is better when compared with the ratio of antimony amount to minimum detection limit.
