n this study, an electrochemical method for the determination of copper ion has been developed using over oxidized polypyrrole
(OPPy) electrode doped with sulfosalicylic acid (SSA). The SSA acts both as a chelating agent and a counter anion within the
polypyrrole matrix. In a typical assay, Cu (II) is accumulated on a solid electrode via the formation of a copper-SSA complex. The
electrode containing the Cu
2+
SSA is then transferred to a 0.2M potassium nitrate where it is subjected to differential pulse anodic
stripping voltammetry. The resulting stripping peak current was linearly related to the concentration of copper. The method has
been optimized with respect to pH (pH=5.0), concentration of chelating agent (0.1M), accumulation time (200s) and reduction
potential (0.5V). The detection limit was found to be 4×10
-9
M with a linear range of 1×10
-9
-1×10
-3
M. The method has been
validated for the determination of copper in environmental samples.
