Gas-phase advanced oxidation (GPAO) for benzene-containing gas by an ultraviolet irradiation/hydrogen peroxide vapour (UV/[H₂O₂]_g) process.

ABSTRACT: Hydrogen peroxide (H₂O₂) is a remarkably strong oxidant, and its vapour ([H₂O₂]_g) has further advantages, such as a low cost and good light transmission. However, there has been very little research on its removal through gas-phase advanced oxidation (GPAO). In the present study, the photochemical oxidation of a gas that contains a series of benzene derivatives using ultraviolet (UV) irradiation and [H₂O₂]_g was investigated in a transparent bag made of fluorinated ethylene propylene (FEP). UV and [H₂O₂]_g barely reduced the pollutant within 5 h when used alone, and the reactant was also stable. When the pollutant concentration was high (248 to 756 mg/m³) and th
