Electrochemical Study On The Anodic Process Of Fes, Hong-Hui Xu
Journal of Electrochemistry
Ferrous sulfide (FeS) was synthesized with spectrum-pure Fe and S at high-temperature, and its anodic behaviors in the solution of 0.5 mol·L~(-1) H_2SO_4 + 0.5 mol·L~(-1) K_2SO_4 was studied by using voltage sweep and step voltage techniques. The effects of acidity on the anodic polarization curves of FeS were investigated. The transfer coefficient β and exchange current density I_0 in the anodic electrode process, and the solid diffusion coefficient D_(Fe) of Fe~(2+) in FeS were measured. And also the activation energies of anodic reaction at different voltages was also determined.

In this study, ethylenediaminetetraacetic acid disodium salt (Na_2EDTA), triethanolamine(TEA), and 2,2′-dipyridine were adopted as chelating agents or additives in the electrolyte for electroless copper plating, and formaldehyde (HCHO) was as the reducting agent. Linear sweep voltammetry was applied to analyze the polarization behavior. The peak current of formaldehyde oxidation which increased by the addition of 2,2′-dipyridine is beneficial to formaldehyde oxidation in a specific range of concentration, While TEA decreased the peak current of formaldehyde oxidation. Two cathodic peaks due to copper(Ⅱ)reduction of TEA chelatation and copper(Ⅱ)reduction of EDTA chelatation were examined. EDTA increased the reduction peak current of Cu-EDTA …
