摘要

Abstract

It was found that the yield of hydroxyl radicals produ ced inCo(II)-H2O2 system was 100 times more than that produced in Fenton reaction. A fluorimetry method for the determination of hydroxyl radicals was developed based on salicylfluorone (SAF)-Co(II)-H2O2 system. The excitation and emission wavelengths were chosen at 500 nm and 510 nm. With measurement of fluorescence intensity, the content of hydroxyl radicals in the solution was successfully determined. The results of clearing experiment and ESR showed that the method was effective and reliable. This sensitive method can be applied to sieve the hydroxyl radical scavenger.
