Kinetic Studies on Reactions Between Monomethylhydrazine and Fe^3＋ as Well as N,N-Dimethylhydroxylamine and Fe^3＋ by Measuring Potential of Fe^3＋/Fe^2＋

The kinetic studies on the reactions between monomethyldrazine and Fe^3＋ as well as N,N-dimethyl- hydroxylamine and Fe^3＋ in nitric acid system are performed by measuring open-circuit potential of Fe^3＋/ Fe^2＋. The effect of some factors such as the concentration of MMH or DMHAN, the concentration of nitric acid, ionic strength, temperature and the concentration of Fe^3＋ on the reaction rate is also studied.
