Wet Oxidation of Mixed Resins by aModified Fenton’s Reaction with an Electrochemical Potential
E-mail:
Wet oxidation of mixed exchange resins were evaluated by changing the catalyst, the contents of the catalyst and the volume of H2O2, with or without an electrochemical potential. H2O2 of over 150 mL was required in order to decompose 5 g of the dried resin at over 95 % with a 0.0045 mole of Fe(II), and an individual 0.0025 mole of Fe(II) and Cu(I) in a co-catalyst system. However only 125 mL of H2O2 and 0.001 mole of both Fe(II) and Cu(I) in a system with an electrochemical potential were required to decompose the same amount of dried resin. When a 0.771 voltage was applied to the solution, the total content of the mixed catalysts was decreased to 50 % for the same decomposition ratio. So the volume reduction effects of a solidified form of a residual inorganic material could be increased by two times.
