Photodegradation of 17β-estradiol induced by Chlorella vulgaris

Abstract

Abstract: The study showed that when exposed to high-pressure Hg-lamp (HPML,λ_max≥365 nm),and the concentration of Chlorella vulgaris was 4.0×10¹⁰ cells·L^-1,the photodegradation rate of 17β-estradiol could reach to 37%.When the concentration of Chlorella vulgaris was 4.2×10¹⁰ cells·L^-1,the photodegradation of 1.5×10^-5～6.0×10^-5 mol·L^-117β-estradiol in aqueous solutions was pseudo-first order reaction.Increasing the initial concentration of 17β-estradiol could lower its photodegradation rate.The influence of light intension and Chlorella vulgaris concentration on the photodegradation of 17β-estradiol was also studied in this paper.

Key words: Photodegradation, Chlorella vulgaris, 17β-estradiol
