MATHEMATICAL-MODELING OF RADIATION-CHEMICAL PROCESSES IN HNO3 SOLUTIONS OF PU .5. EFFECT OF [HNO3] ON RATE CONSTANTS OF RADIATION-CHEMICAL AND CHEMICAL-REACTIONS OF PU IONS

Dependences of rate constants on [HNO3] are obtained for the reactions Pu(IV) + OH, Pu(IV) + NO3, Pu(V) + NO2, Pu(III) + NO2, Pu(V) + Pu(III), Pu(IV) + Pu(IV), and Pu(V) + Pu(V). These dependences are obtained for [HNO3] = 0.3-6 M using existing experimental and literature data and our data obtained using mathematical modeling. The correctness of the resulting dependences is checked by comparing the calculated and experimental kinetic laws for the behavior of Pu in 0.3, 0.4, 0.6, and 1.6 M HNO3.
