摘要/Abstract

摘要： 利用室内和室外模拟实验研究了光强、温度、溶解氧、 pH值和腐殖质等因素对 α-萘酚光降解的影响. 通过测定α-萘酚在天然水体中光化学反应的量子产率，推算出其光降解半寿命的理论值. 其理论值与实测值基本一致.

关键词: α-萘酚, 光降解, 量子产率

Abstract: The effects of light intensity, temperature, dissolved oxygen, pH value and hu mic acid on the degradation of α-naphthol were investigated, respectively, by means of indoor and outdoor simulation experiments. The quantum yields of the p hotoreact ions of α-naphthol in natural water were determined. On the basis of which its theory half-lives of photodegradation of α-naphthol were deduced also, whi ch were coincident with the actually determination values.

Key words: α-naphthol, photodegradation, quantum yield
