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 reactivity of an immobilized layer (nafion-en) to yield complex <TEX>$[Cu(en)_2]^{+2}$</TEX>. The reduction potential peak by differential pulse voltammetry(DPV) was observed at -0.4402V(<TEX>${\pm}0.0050V$</TEX>) (vs. Ag/AgCl). The linear calibration curve was obtained from <TEX>$1.0{\times}10^{-6}$</TEX> to <TEX>$1.0{\times}10^{-4}M$</TEX> copper(II) ion concentration, and the detection limit(3s) was <TEX>$1.96{\times}10^{-6}M$</TEX>.
