摘要：

The electrochemical behavior of a cobalt(II)-heptacyanonitrosylferrate (CoHNF) film on a glassy carbon electrode has been investigated. Cyclic voltammetry shows a single electron-transfer reaction taking place at 0.51 V for the modified electrode. The ion effect of the supporting electrolyte indicates that the ion permeability in the CoHNF film is mainly determined by the hydrated radius of cation. The modified electrode catalyzes redox reactions of the Fe2+/Fe3+ couple. It also exhibits a linear potentiometric response over the range of 3x10(-5) - 1x10(-2) M NO2- with a near-Nernstian slope in an acidic medium.
