Abstract

Absorbance measurements find the yield of the oxidation of U(IV) to be (8.75 ± 0.05) × 10-7 mol J-1 in the 60Co γ radiolysis of aqueous solutions containing 4.4 × 10-3 mol L-1 U(IV) in the presence of O2 saturated 2 mol L-1 Cl- at pH = 0. This high value of oxidation yield suggests that all primary radicals formed by water decomposition are scavenged in these solutions. Simulations using a nonhomogeneous stochastic kinetic track model agree with the experimental results and are used to explain the mechanism for scavenging radicals and oxidation of U(IV). © 2009 American Chemical Society.
