Abstract

Fe 3+ can be slowly reduced to Fe 2+ by monomethylhydrazine, 1,1 dimethylhydrazine and 2 hydroxylethylhydrazine as a reductant. Apparent rate constants for the reactions are determined to be 0.023, 0.11 and 0.45 min -1 at 293 K, respectively. The resultant Fe 2+ ions can quickly reduce Np(Ⅵ) to Np(Ⅴ) and Fe 2+ convert to Fe 3+ . Fe 3+ ion seems to be a catalyst for reduction of Np(Ⅵ). Based on experimental results, a kinetic equation of the Fe 3+ ion as function of the rate of Np(Ⅵ) reduction is obtained.
