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: -d[U(IV)]/(dt)=0.14[U(IV)][HNO_2]^(0.55)/[NHO_3]^(0.43) 和-(d[NHO_2]/(dt))_消=0.16[HNO_2][HNO_3]亚硝酸的变化速率为: d[HNO_2]/(dt)=0.14[U(IV)][HNO_2]^(0.55)/[HNO_3]^(0.43)-0.16[HNO_2][HNO_3]
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:-d[U(IV)]/dt=0.14[U(IV)][HNO_2]^(0.55)/[HNO_3]^(0.43)and-d[HNO_2]/dt=0.16[HNO_2][HNO_3]respectively, and the overall reaction rate equation for nitrous acid is:d[HNO_2]/dt=0.14 [U(IV)][HNO_2]^(0.55)/LHNO_3]^(0.43)-0.16[HNO_2][HNO_3]
