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 H₂SO₄ + 0.5 mol·L^-1 K₂SO₄ 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 Fe²⁺ in FeS were measured. And also the activation energies of anodic reaction at different voltages was also determined.
