자외선 조사에 의한 벤젠의 광증감 산화처리에 관한 연구

Photo-sensitized oxidation of benzene in water under UV irradition

이춘식, 이동근

초록

광증감제로서 과황산 이온, 황산 이온, 질산 이온, 아질산 이온 및 염소 이온을 이용한 반응조건하에서 수용액중 벤젠의 광증감 산화반응을 조사하였다. 과황산 이온이 가장 효과적인 광증감제로 나타난 반면, 황산 이온 및 아질산이온은 벤젠의 광증감 산화반응에 증감역할을 수행하지 못하였다. 아질산 이온은 다른 이온과 공존할 때 생성된 ㆍOH라디칼을 소멸시켜 벤젠의 광증감 산화반응을 저해하는 것으로 나타났다.

The photo-sensitized oxidation of benzene in water was investigated under various reaction conditions using persulfate, sulfate, nitrate, nitrite and chloride ions as sensitizers. Persulfate ion was proved to be the most effective sensitizer, while sulfate and nitrite could not play any sensitizing role on the benzene photooxidation. When exited together with other ions, the nitrite ion inhibited the photooxidation of benzene by quenching the produced hydroxyl radicals.
