摘　　要：[目的]选用典型阴离子表面活性剂十二烷基苯磺酸钠,探讨其在不同条件下的降解行为。[结果]十二烷基苯磺酸钠的光降解速率随着光照强度的增加而增加;在蒸馏水中的效果较人工海水中的好;随着初始质量浓度的增加而降低。[结论]十二烷基苯磺酸钠的光降解速率与光照条件、介质、初始质量浓度都有关系,并且不同的表面活性剂光降解影响因素不同。[Aims] Sodium dodecylbenzene sulfonate （SDBS） was selected as the typical anionic surfactant, and its degradation efficiency under different conditions were studied. [Results] The results showed that photic degradation rate of SDBS increased along with the illumination intensity. SDBS showed higher degradation in distilled water than that in artificial seawater, and decreased faster with the increase of the initial concentration. [Conclusions] The photic degradation rate of SDBS was related to illumination condition, medium, initial concentration. And also the factors effecting on the photodegradation depended on the type of surfactant.
