摘要
研究了普通小球藻、铜绿微囊藻和柱孢鱼腥藻3种藻类引发水中17α-乙炔基雌二醇（EE2）的光降解。结果表明，在250W高压汞灯（HPML，nm）的照射下，一定藻浓度下，EE2的光降解率可达19％～20％。另外，还研究光强、藻悬浮液浓度和EE2初始浓度等对EE2光降解速率的影响，发现在本实验体系中，光通量大、藻浓度高及EE2初始浓度低有利于提高EE2的光降解速率。
The effects of Chlorella vulgaris, Microcytis aeruginasa kutz and Anabaena cylindricaon on the photodegradation of 17α-ethynylestradiol （EE2） were reported. As a result, exposed to high-pressure Hg-lamp （HPML,λmax ≥365 nm） , as the concentration of alage were certain, the rate of 17α-ethynylestradiol photodegradation could reach to 19%- 20%. Increasing the initial concentration of 17α-ethynylestradiol lower the photodegradation rate. Moreover, the influence of light intension and the concentration of Chlorella vulgaris, Microcytis aeruginasa kutz and Anabaena cylindricaon on the photodegradation of 17α-ethynylestradiol were also studied here. As a result, higher luminous flux, higher algae content and lower initial content of EE2 made good for photodegradation rate of EE2.
