【Abstract】 The influence of temperature, concentration ratio, pH and copper (Ⅱ) on the directional reaction of N2H4 with iron(Ⅲ) has been studied. The reaction of iron (Ⅲ) with N2H4 prefers to one-electron reaction. Simultaneously, four-electron reaction exits partially.The ratio of four-electron reaction of N2H4 increases as raising pH volue,[Fe(Ⅲ)]0/[N2H4]0 concentration ratio, temperature and as adding copper(Ⅱ) into the reaction mixture.更多还原
