普通小球藻引发水中17β-雌二醇的光降解

摘要/Abstract

摘要： 研究了普通小球藻引发水中17β-雌二醇(E2)的光降解,结果表明,在250 W高压汞灯(HPML,nm)的照射下,藻浓度为4.0×10¹⁰个·L^-1时,17β-雌二醇的光降解率可达37%.藻浓度为4.2×10¹⁰个·L^-1时,17β-雌二醇浓度在1.5×10^-5-6.0×10^-5mol·L^-1范围内,其光降解速率与初始浓度成正比,反应是假一级.另外,还研究光强、藻悬浮液浓度和17β-雌二醇初始浓度等对此反应体系的影响.

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.
