| Outline of Final Research Achievements |
Acceleration of redox cycle of Fe(III) was examined to degrade non-biodegradable organics, which are hard to be degraded by conventional method, by continuous generation of OH radicals upon Fenton oxidation. Copper ions work as catalyst for the reduction of Fe(III) by organics, and 94% of phenol can be converted to CO2 when C(II) is added to Fenton reagent. Reduction of Fe(III) can be also achieved by photochemical reduction with oxalic acid, which is one of the organic ligands for Fe(III), and by electrochemical reduction. Both methods enable to reduce 1,4-dixane concentration to less than 0.5 mg/L.
