REMOTION OF ORGANIC-COMPOUNDS OF ACTUAL INDUSTRIAL EFFLUENTS BY ELECTRON-BEAM IRRADIATION

Organic compounds has been a great problem of environmental pollution, the traditional methods are not efficient on removing these compounds and most of them are deposited to ambient and stay there for long tim e causing problems to the environment. Ionizing radiation has been use d with success to destroy organic molecules. Actual industrial effluen ts were irradiated using IPEN's electron beam wastewater pilot plant t o study organic compounds degradation. The samples were irradiated wit h and without air mixture by different doses. Irradiation treatment ef ficiency was evaluated by the Cromatography Gas Analyses of the sample s before and after irradiation. The studied organic compounds were: ph enol, chloroform, tetrachloroethylene (PCE), carbon tetrachloride, tri chloroethyiene (TCE), 1,l-dichloroethane, dichloromethane, benzene, to luene and xilene. A degradation superior to 80% was achieved for the m ajority of the compounds with air addition and 2kGy delivered dose con dition. For the samples that were irradiated without air addition the degradation was higher.
