Ex situ experiments were performed to quantitatively determine the effect of Ce(III) on the generation of hydroxyl HO radicals and of carbon-centered radical adducts in Nafion dispersions exposed to HO radicals, and on the generation of the RCF2CF2 radicals in Nafion membranes during the photo-Fenton reaction. Addition of Ce(III) has profound effects on the decrease of radical fragments in Nafion membrane and membrane dispersions. The rate constant for scavenging of hydroxyl radicals by Ce(III), 6 x 108 M/s, was determined in spin trapping experiments.
