摘要
本文研究了阴离子表面活性剂ＤＢＳ在光氧化过程中，光强度、光照射间、催化剂用量、ｐＨ等因素对分解速度的影响，同时还讨论了ＤＢＳ处于嫩江自然水环境中，于阳光照射下分解的速率常数和半衰期。
The effects of intensity of light,irradiation time,pH and concentration of catalyst on the photodegradation of anionic surfactants DBS. The rate of photodegradation of DBS in Nen Jiang water was determined under sunlight,the rate constant and half-life of DBS were found.
