氨基羟基脲与Pu(IV)的还原动力学研究

The kinetics of reaction between Pu(Ⅳ) and hydroxysemicarbazide (HSC) in nitric acid solution was studied. The rate equation is found to be: -dc(Pu(Ⅳ))/dt=kc(Pu(Ⅳ))c^1.06 (HSC)c^(-0.43) (H(superscript +))c^(-0.58) (NO(superscript - subscript 3)), where k=(11.8±1.1) (mol/L)^(-0.046)•s^(-1) at 22.1℃ and the activation energy E(subscript a)=(71.0±1.0) kJ/mol. Effects of c(HSC), c(H(superscript +)), c…
