摘要：

The usefulness of zinc orthophosphate and zinc mercuric thiocyanate to make a carbon-support electrode responsive to zinc was investigated. The best results were obtained with zinc orthophosphate, which produced a Nernstian response to zinc in the concentration range from 10-5 to 10-2M. The electrode response was lowered by the formation of acidic oxides on the surface of the electrode. Different ways of minimizing this problem are discussed. Interference effects from copper(II) (KpotZn.Cu = 1.0), cadmium (KpotZn.Cd = 8.9) and lead (KpotZn.Pb = 10) were observed. © 1990.
