Tartalmi kivonat:Degradation reactions of two beta-blockers, atenolol and propranolol were studied using high energy ionizing irradiation interpreting the outcome of the ongoing radical reactions on the degradation efficiency, oxidation and mineralization processes and toxicity. Under appropriate conditions both hydroxyl radical (•OH) and hydrated electron (eaq ) take part in degradation reactions. Propranolol showed higher reactivity under both oxidative end reductive conditions than atenolol. Thus it is not surprising that the oxidation and mineralization reactions take place more rapidly due to its condensed ring having higher electron density on the aromatic ring in propranolol. During removal of propranolol toxic products, hydroxylated naphthalene derivatives form. Using appropriate doses the starting molecules can be degraded and the toxic character of the end-products can be eliminated.
