Abstract

The study showed that when exposed to high-pressure Hg-lamp (HPML, lambda(max) > or = 365 nm), and the concentration of Chlorella vulgaris was 4.0 x 10(10) cells x L(-1), the photodegradation rate of 17beta-estradiol could reach to 37%. When the concentration of Chlorella vulgaris was 4.2 x 10(10) cells x L(-1), the photodegradation of 1.5 x 10(-5) - 6.0 x 10(-5) mol x L(-1) 17beta-estradiol in aqueous solutions was pseudo-first order reaction. Increasing the initial concentration of 17beta-estradiol could lower its photodegradation rate. The influence of light intension and Chlorella vulgaris concentration on the photodegradation of 17beta-estradiol was also studied in this paper.
