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

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 [Cu²⁺]/[Bi³⁺] 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.
