Abstract
The aim of this study was 1,4-dioxane's degradation efficiency and toxicity test applying E-beam. The experiments were shows that the degradation efficiency in the initial concentration of 1,4-dioxane 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 of green algae, Pseudokirchneriella Subcapitata was conducted to lead the reducing toxicity. Degradation efficiency of 1,4-dioxane was improved when E-beam irradiation intensity was higher and the efficiency of TOC removal using Radical scavenger gas was increased by $N_2O$, $O_2$ and $N_2$ in order. In 4 days(96hrs), toxicity test results indicated that toxicity effect was decreased by increase of E-beam irradiation intensity.
