Abstract
Voltammetry techniques such as cyclic voltammetry and electrochemical impedance spectroscopy are used to quantify metal ions in aqueous solutions. In this paper, we have reported electrochemical detection of lead (II), cadmium (II), and Copper (II) ions based on carbon paste electrode using graphite powder. Potassium ferricyanideK3 [Fe(CN)6] solutions as benchmark media to check redox reactions. The Detection limit was 6.56 × 10–9 M investigated by cyclic voltammetry. Effects of pH and supporting electrolytes were also measured.
