Abstract

A glassy-carbon electrode was modified with cadmium pentacyanonitrosylferrate film using cyclic voltammetry. The voltammetry behavior of the cadmium pentacyanonitrosylferrate on the glassy-carbon electrode shows a redox couple (FeIII/FeII) with E °′ of 593 mV (Ipa/Ipc = 0.96) and ΔEp of 34 mV in 0.5 mol dm-3 KNO3 (ν = 100 mV s-1) with an adsorption-controlled process. The anodic-peak currents of the film decreased in the presence of tetrahydrothiophene due to a reaction of the precipitation on the film surface by a nucleophilic attack. © 2011 Elsevier B.V.
