Title: Phenyfluorene Fluoremetry Assay of Hydroxyl Radical Produced by Sn~(2+)H_2O_2
Abstract: It was found that the yield of Hydroxyl radicals produced in Sn 2+ -H 2O 2 system was 100 times more than that produced in Fenton reaction.A fluorimetry method for the determination of hydroxyl radicals was developed based Phenyfluorene Sn 2+ H 2O 2 system.The excitation and emission wavelength were chosen at 500nm and 510nm.With measurement of fluorescence intensity, the content of hydroxyl radicals in the solution was successfully determined.The results of clearing expericent and ESR showed that the method was effective and reliable.This sensitive method can be applied to sieve the hydroxyl radical scavenger.
