摘要：
The use of a dimethylglyoxime modified Nafion-coated mercury-film electrode in square-wave anodic stripping voltammetry for the determination of copper(II) is described. Compared with a Nafion-coated mercury-film electrode, this modified electrode showed improved resistance to interferences from surface-active compounds and much better selectivity. In addition, detection can be achieved without deoxygenation and the electrode can be easily renewed.
