Abstract: The Cu (II) imprinted polymer glassy carbon electrode (GCE/Cu-IP) was prepared by electropolymerization of pyrrole at GCE in the presence of methyl red as a dopant and then imprinting by Cu2+ ions. This electrode was applied for potentiometric and voltammetric detection of Cu2+ ion. The potentiometric response of the electrode was linear within the Cu2+ concentration range of 3.9 x 10-6 to 5.0 x 10-2 M with a near-Nernstian slope of 29.0 mV decade-1 and a detection limit of 5.0 x 10-7 M. The electrode was also used for preconcentration anodic stripping voltammetry and results exhibited that peak currents for the incorporated copper species were dependent on the metal ion concentration in the range of 1.0 x 10-8 to 1.0 x 10-3 M and detection limit was 6.5 x 10-9 M. Also the selectivity of the prepared electrode was investigated. The imprinted polymer electrode was used for the successful assay of copper in two standard reference material samples
