Information
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: N2O> O2> N2, The toxicity test showed that the toxicity effect
after 4 days(96hrs) was decreased by increase of E-beam irradiation intensity.
본 연구의 목표는 전자빔 공정을 적용하여 Triclosan의 제거효율 및 독성평가를 하는 것이다. 이 실험에서는 전자빔 선량과
Triclosan의 초기 농도에 따른 저감 효율 및 스캐벤저 가스에 따른 무기화의 정도를 알아보았다. 또한 녹조류 중 하나인 Pseudokirohneriella
Subcapitata를 이용하여 생물독성과 위해성 평가를 통한 독성저감기술을 시험하였다. 그 결과 Triclosan은 전자빔 조사량이 증가할수
록 분해 효율이 향상되었고, 라디칼 스캐벤저 가스에 의한 TOC 제거는 N2O나 O2를 용해시켰을 때 효율이 증가된 것으로 나타났다.
4일(96hrs) 후 독성평가 결과 전자빔 조사 강도의 증가에 따라 독성 영향이 저감되는 것을 알 수 있었다.
