A fluorescent dye light green SF(LGSF) can produce its characteristic fluorescence peak in diluted sulfuric acid at 312 nm.The fluorescence can be quenched by the hydroxyl radical OH produced by Fenton reaction.By measuring the change of the fluorescence intensity of LGSF,the OH content can be determined indirectly under optimum experimental conditions.The results show that this method is stable,simple and rapid.The method can be used as a convenient way for the selection of hydroxyl radical scavengers for its good stability,and can be applied to determine and monitor hydroxyl radicals on line.
