The electrode reactions of the Fe(II)-NCS system occurring at mercury electrodes have been studied by using cyclic voltammetry and large scale electrolysis. The elatroreduction of Fe(H) in that system occurs with a fast transfer of the first electron. The resulting intermediate complex of iron(I) is further reduced to metallic iron and partly decomposes to yield FeS which is adsorbed on the electrode surface. Its adsorption initiates the surface deposition of the iron not wetted by mercury. This deposition was further studied by chronoamperometry. The oxidation of deposited iron, which occurs in two peaks, was also investigated in detail. Also the surface transformation of FeS into HgS as well as the electroreduction of HgS in presence of Fe(H) was studied.
