The cyclic voltammetry, current-time curve at potential step were used to investigate the electrochemical behavior of Fe(Ⅱ) in DMSO, DMF and CH3CN solutions on Pt cathode. Experimental results indicate that the electroreduction of Fe(Ⅱ) to Fe(0) is irreversible in one step on Pt electrode. The diffusion coefficients of Fe(Ⅱ) in DMSO, DMF and CH3CN solutions at 298 K were determined to be 2.3×10-6, 1.32×10-6 and 2.5×10-6 cm2*s-1, respectively. The transfer coefficients of Fe(Ⅱ)+2e→Fe(0) in DMSO, DMF and CH3CN solutions were determined to be 0.11, 0.10 and 0.06, respectively.
