Study of nitroxide-linked naphthalene as a fluorescence probe for hydroxyl radicals
- 化学化工－已发表论文 
A novel technique for the determination of hydroxyl radical is described. The method employed the reaction of hydroxyl radical with dimethyl sulfoxide quantitatively to generate a methyl radical, which then coupled with nitroxide-linked naphthalene and led to a large increase in fluorescence intensity. The fluorescence increment was proportional to the concentration of hydroxyl radicals down to 1 x 10(-7) mol l(-1). The proposed method was demonstrated to be capable of detecting hydroxyl radicals generated in Fenton systems. It proved to be a simple and sensitive technique for the determination of hydroxyl radicals. (C) 2001 Elsevier Science B.V. All rights reserved.
