This study was aimed to investigate the effect of oxidants on biodegradability anddecomposition of acetaminophen (ACT) by gamma ray. Three kinds of chemical, potassiumpersulfate, hydrogen peroxide and ferrous sulfate were selected as an oxidant. The absorbed dosewas ranged from 0.2 to 10 kGy and the concentration of oxidants was from 0.1 to 10 mM and theinitial concentration of acetaminophen was 30 mg l-1 in this study. The concentration of ACT wasgradually decreased corresponding to the increase of the absorbed dose. However, mineralizationof ACT was not occurred by the increased of the absorbed dose. When the 10 mM of oxidantsapplied to the ACT aqueous solution, the concentration of ACT was rapidly decreased accordingto absorbed dose and the mineralization was observed in potassium persulfate. Biodegradabilityof ACT with potassium persulfate was higher than that of ACT without potassium persulfate inlower absorbed dose and decreased according to higher absorbed dose.
