Abstract

The influence of acidity, hydroxylamine concentration, temperature, and time on the pretreatment effect have been studied. An approximate reaction rate equation of the systems studied has been obtained as follows:r=K[RuNO]2.5[H2NOH]1.3[HNO3]−1.0. The pretreatment effect is obvious at low acidity. which makes the Ru distribution coefficient decrease by ten times.
