摘要

采用高温合成法由光谱纯的Fe和S制备FeS,并应用电位扫描和电位阶跃法研究FeS在0.5mol·L-1H2SO4+0.5mol·L-1K2SO4溶液中的阳极电化学行为.考察酸度对FeS阳极极化的影响,测定阳极过程的传递系数β、交换电流I0和Fe2+在FeS中的固相扩散系数DFe以及不同电极电位下阳极电化学反应活化能ΔEa.

Abstract

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.
