The method employed the reaction of hydroxyl radical with dimethyl sulfoxide to generate a methyl radical quantitatively, which then coupled with the nitroxide linked naphthalene and led to a large increase in fluorescence intensity. The proposed method was demonstrated to be capable of detecting hydroxyl radicals generated in the Fenton systems.

文摘A novel technique for the determination of the hydroxyl radical is described in this paper. The method employed the reaction of hydroxyl radical with dimethyl sulfoxide to generate a methyl radical quantitatively, which then coupled with the nitroxide linked naphthalene and led to a large increase in fluorescence intensity. The proposed method was demonstrated to be capable of detecting hydroxyl radicals generated in the Fenton systems. It proved to be a simple and sensitive technique for the determination of hydroxyl radicals.
