Title: Determination of Hydroxyl Radicals by Flow Injection Fluorometry
Abstract: A novel method has been developed for the determination of hydroxyl radicals in Fenton reaction by flow injection fluorometry. Ce~(3+ )can produce its characteristic fluorescence in diluted sulfuric acid and its fluorescence is quenched when Ce~(3+ )is oxidized by hydroxyl radical. The content of hydroxyl radical in the solution can be indirect determined by measuring the decrease of fluorescence intensity. The method can be applied to on line determination of hydroxyl radicals and screen the antioxidants.
