水环境中α-萘酚光降解的研究

Studies on the Photodegradation of α-Naphthol in Natural Water

利用室内和室外模拟实验研究了光强、温度、溶解氧、p H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 .

The effects of light intensity, temperature, dissolved oxygen, pH value and humic acid on the degradation of α-naphthol were investigated, respectively, by means of indoor and outdoor simulation experiments. The quantum yields of the photoreactions 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, which were coincident with the actually determination values.
