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