Simultaneous Determination of Bismuth and Copper by Square Wave Voltammetry in The Presence of Ethylenediaminetetraacedic Acid

A sensitive and selective method for the simultaneous determination of copper and bismuth by square wave voltammetry insert ignore into journalissuearticles values(SWV); was developed using ethylenediaminetetraacedic acid insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(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.
