  • 摘要: 研究了普通小球藻引发水中苯胺的光降解,结果表明:在250W高压汞灯(λ≥365nm)的照射下,藻浓度为2.0×1010个·l-1时,苯胺的光降解率可达37%;苯胺浓度为0.004-0.02mmol·l-1范围内,苯胺的光降解速率与初始浓度的降低成反比,反应是假一级.另外,还研究了光强、藻悬浮液浓度和苯胺初始浓度等对反应体系的影响.
    Abstract: The effects of C. vulgaris on the photodegradation of aniline was reported.As a result,exposed to high pressure Hg lamp(250w, λ max ≥365nm),as the concentration of C. vulgaris is 2.0×1010-1, the rate of anilines photodegradation could reach to 37%;when aniline concentrations are between 0.004—0.02mmol·l-1,the relation between the rate of ainiline photodegradation and the anilines inital concentration belongs to inverse ratio.Moreover,the influence of light intension,the concentration of C. vulgaris and initial aniline on the photodegradation of anilines was also studied.
