A high-performance liquid chromatography system with Fenton's reagent for detection of gas-phase hydrogen peroxide
type: CreativeWork
description: A simple quantitative HPLC method for analysis of gas-phase hydrogen peroxide (H2O2) has been developed. This method relies on conversion of sodium salicylate to dihydroxybenzoic acid, sodium salts by using Fenton's reagent (a mixture of H2O2 and ferrous iron) under the proper conditions. Hydroxyl radicals generated from Fenton's reagent will react with sodium salicylate and generate 2,3-, 2,4-, and 2,5-dihydroxybenzoic acid (sodium salts), which can be quantitatively determined by HPLC-UV at wavelength 310 nm. The cryogenic sampling system was chosen to collect gasphase H2O2. The detection limit for this method is 0.03 ppm. The seasonal variation of H2O2 in Las Vegas was observed, and the correlations between the concentrations of O3, CO, NOx, and that of H2O2 were studied.
