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