Optimization of photochemical oxidation processes for MTBE degradation using electron spin resonance spectroscopy

Abstract

Optimization of Photochemical Oxidation Processes for MTBE Degradation using Electron Spin Resonance Spectroscopy was designed to study the influence of different monochromatic UV-light sources, hydrogen peroxide (H2O 2) and Ozone (O3) as photochemical oxidizers. The study focused on maximizing hydroxyl radical produced by UV/H2O2, UV/O3, and UV/H2O2/O3 through direct measurement of hydroxyl radical using ESR. This study provided comprehensive understanding of specific UV light regions that affect the photochemical oxidation processes, and employed radical trapping using ESR to optimize experimental parameters using aforementioned parameters to maximize hydroxyl radical production. The optimized parameters were tested on removal of MTBE from contaminated water
