Electron beam decomposition of pollutant model compounds in aqueous systems

Application of ionizing radiation for recalcitrant organic decomposition has been well documented for such compounds as methyl tert-butyl ether (MTBE) [3], phosphonic acid, dimethy ester [17], 2,4-dichlorophenoxyacetic acid [6], aromatic hydrocarbons [12], benzene, toluene, m-xylene, o-xylene [16], THMs [5], bromate [21], phenol [14], methyl isobutyl ketone, toluene, xylene, tetrachloroethylene (PCE), trichloroethylene (TCE) [7, 8] and others. Studies on the decomposition of many other individual pollutants using various advanced oxidation processes can be found in the literature, e.g. a review on the decomposition of biphenols, alkylphenols and phthalates by advanced oxidation processes [10]. Industrial activities are well known of generating wastewater that lead to the environmental degradation which has become a serious problem. Wastewater generated from industry has a high complexity of pollutants which include hazardous and toxic materials. For example, in the textile industry wastewater effluent is consisted of a mixture of many individual pollutants. Although ionizing radiation has been regarded as effective method to decompose individual pollutant by analyzing the concentration of individual pollutant, the efficiency and effectiveness of decomposition after irradiation are influenced by many factors.
