摘要：

The technique for developing a screen-printing disposable carbon electrode and modifying its surface with electropolymer of catechol-formaldehyde was described. This modified electrode could be used to determine the Cu2+ with high selectivity. The linear range of the determination was from 2.5 mug/L to 50 mug/L. The linear regression coefficient and the RSD were 0.9992 and 2.7%, respectively. The content of Cu2+ in local tap water was determined by this modified electrode for 6.27 mug/L.
