| Outline of Final Research Achievements |
The purpose of the present study is to develop the supported catalysts that can selectively and efficiently degrade bromophenols in the presence of humic acids, which can serve as inhibitors for oxidative degradation of organic pollutants. First, to remove humic acids from the active sites in the catalysts, a mesoporous silica-supported iron(III)-porphyrin catalyst was synthesized. Bromophenols were selectively degraded by this catalyst, even in the presence of 50 mg/L humic acid. In addition, ionic liquid was modified on the silica-coated magnetite and an iron(III)-porphyrin catalyst was then introduced into this support. More than 50% of bromophenols was mineralized to CO2 by using this supported catalyst.
