| Abstract | A High Performance Liquid Chromatography System with Fenton's Reagent for Detection of Gas-Phase Hydrogen Peroxide by Jun Liu Dr. Spencer M. Steinberg. Examination Committee Chair Professor o f Chemistry University of Nev^ada, Las Vegas .4 simple quantitative HPLC method for analysis of gas-phase hydrogen peroxide has been developed. This method relies on conversion o f sodium salicylate to dihydroxybenzoic acid, sodium salts by using Fenton's reagent (a mixture o f 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 2,5dihydroxybenzoic acid (sodium salts), which can be quantitatively determined by HPLCUV 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 o f O3, CO, NOr and that of H2O2 were studied. |
