摘　　要：Methyl hydrazine (MMH) is a supporting reagent used in the Purex process in order to eliminate nitrous acid in the system. The reaction between MMH and Tc(Ⅶ) in nitric acid medium was studied by extraction method. The influences of temperature, acidity, the concentrations of MMH andMethyl hydrazine （MMH） is a supporting reagent used in the Purex process in order to eliminate nitrous acid in the system. The reaction between MMH and Tc（Ⅶ） in nitric acid medium was studied by extraction method. The influences of temperature, acidity, the concentrations of MMH and pertechnetate on the reaction is investigated. The results indicate that the reaction period is composed of three stages, induction period, fast reaction period and the termination of the reaction.
