摘要：

This paper describes a potentiometric method for the determination of Cu2+ in 0.1 mol/L HAc-NaAc -1.0mol/L NaCl buffer, pH 5.00, using a carbon paste electrode, whose linear range is 1.0x 10(-6)similar to 1.0x10(-3) mol/L with 61mV/decade of calibration slope. It exhibits high selectivity and desired reproducibility.
