Abstract :A sensitive and selective method for the simultaneous determination of copper and bismuth by square wave voltammetry (SWV) was developed using ethylenediaminetetraacedic acid (EDTA) as complexing agent. Factors affecting the pH and concentrations ratios of copper and bismuth were investigated. Optimal analytical conditions were found to be: pH of 8.0, the ratio of [Cu 2+ ]/[Bi 3+ ] was 0.13-2.5. The limit of detection (3δ) was 1.26 × 10 -7 mol dm -3 for copper, 1.30×10 -7 mol dm -3 for bismuth. Key Words: Copper; Bismuth; Simultaneous determination; SWV; EDTA; Water.Keywords :
