| Research Abstract |
The effects of solid ceramic oxides on the radiation-induced reactions in aqueous solutions were studied. The reduction of dichromate ion in the presence of silica gel and the production of hydrogen and hydrogen peroxide in the presence of zeolites were investigated using-radiolysis technique. Based on the results, inhibition of the oxidation by hydroxyl radical was proposed as an important effect of oxides on the radiation-induced reaction. Moreover, the inhibition of the reaction of hydroxyl radical was observed in aqueous solution of nano-sized colloidal silica directly by time-resolved absorption spectroscopy using pulse-radiolysis technique.
