Abstract

Copper(II) ion was measured with the use of a perfluorinated sulfonated polymer-ethylenediamine(nafion-en) modified glassy carbon electrode. The electrode mechanism was based on the chemical reactivityof an imobilized layer (nafion-en) to yield complex [Cu(en)2]+2. The reduction potential peak by diferentialpulse voltametry(DPV) was observed at -0.4402V(±0.0050V) (vs. Ag/AgCl). The linear calibration curve wasobtained from 1.0×106 to 1.0×104M copper(II) ion concentration, and the detection limit(3s) was 1.96. 106M.
