Abstract
The abjective of this study was to study the degradation behavior and acute toxicity assessment of Triclosan and acute toxicity under E-beam irradiation. The experiments were conducted to investigate the efficts of the degradation efficiency in the initial concentration of Triclosan and the irradiation capacity of E-beam and the degree of mineralization based on a change of scavenger gas. The biological toxicity test by using on green algae, Pseudokirchneriella Subcapitata was conducted to lead the reducing toxicity. Degradation efficiency of Triclosan was improved when E-beam irradiation intensity was higher. Additionally, the % of TOC removal in each Radical scavenger gas was increased as the follows orders: $N_2O$ > $O_2$ > $N_2$, The toxicity test showed that the toxicity effect after 4 days(96hrs) was decreased by increase of E-beam irradiation intensity.
