【Abstract】 The photodegradation of 17α ethynylestradiol(EE 2)in aqueous solutions was induced by UV light ( λ =254?nm, 30W). Over the range of 1.0 — 25 ?mg/L, Photodegradation of EE 2 was pseudo first order reaction. The photodegradation efficiency of EE 2 increased with increasing solution pH over the range of 5—8. Ferric ions could enhance the photodegradation of EE 2 in aqueous solutions at pH of 4.0—6.0.更多还原
