摘要：

Liquid chromatography was used indirectly to detect hydroxyl radicals after a trapping reaction with salicylic acid in an advanced oxidation process. Through the quantitative determination of primary hydroxylated derivatives of salicylic acid, the concentration of hydroxyl radicals was evaluated relatively. Factors affecting the trapping reaction, such as the ratio of salicylic acid to hydrogen peroxide and trapping time, as well as the applicability of the method, were investigated. From the low relative standard deviation for replicate tests under controlled conditions, the method was found to be applicable to the determination of the generation rate or the concentrations of hydroxyl radicals in advanced oxidation processes for water treatment.
