REACTION OF NITROUS ACID WITH U(Ⅳ) AND NITRIC ACID IN 30% TBPKEROSENE SOLUTION

摘要: 文章研究了TBP相亚硝酸同轴(IV)和硝酸的反应,通过实验,求得亚硝酸氧化铀(IV)和亚硝酸与硝酸反应速率的经验式,它们分别为: -dU(IV)/(dt)=0.14U(IV)HNO_2~(0.55)/NHO_3~(0.43) 和-(dNHO_2/(dt))_消=0.16HNO_2HNO_3亚硝酸的变化速率为: dHNO_2/(dt)=0.14U(IV)HNO_2~(0.55)/HNO_3~(0.43)-0.16HNO_2HNO_3

Abstract: Reaction of nitrous acid with U(IV) and nitric acid in 30% TBP-kerosene solution is investigated, the rate equations of oxidation of U(IV) bynitrous acid and that of nitrous acid reacting with nitric acid can be expressed as:-dU(IV)/dt=0.14U(IV)HNO_2~(0.55)/HNO_3~(0.43)and-dHNO_2/dt=0.16HNO_2HNO_3respectively, and the overall reaction rate equation for nitrous acid is:dHNO_2/dt=0.14 U(IV)HNO_2~(0.55)/LHNO_3~(0.43)-0.16HNO_2HNO_3
