Utilization of Solar Energy in the Photodegradation of Gasoline in Water and of Oil-Field-Produced Water

摘要

The photo-Fenton process utilizes ferrous ions (Fe~(2+)),hydrogen peroxide (H_2O_2),and ultraviolet (UV) irradiation as a source of hydroxyl radicals for the oxidation of organic matter present in aqueous effluents.The cost associated with the use of artificial irradiation sources has hindered industrial application of this process.In this work,the applicability of solar radiation for the photodegradation of raw gasoline in water has been studied.The photo-Fenton process was also applied to a real effluent,i.e.,oilfield-produced water,and the experimental results demonstrate the feasibility of employing solar irradiation to degrade this complex saturated-hydrocarbon-containing system.
