Photodegradation of Azithromycin in Aqueous System Under VIS/UV Irradiation

Xinghan Chen

Abstract

Antibiotics, such as azithromycin, have become one major group of emerging contaminants in aquatic systems. It is urgent to explore efficient, safe, and economic methods to removal azithromycin in aquatic environment. This paper described the photolysis of azithromycin and its affecting factors (initial concentration of azithromycin, pH, nitrate and Fe (III)-oxalate complexes) under visible and UV light irradiation. The results indicated ultraviolet has stronger ability to degrade azithromycin than visible light. The photodegradation efficiencies of azithromycin decreased with the increase of its initial concentration under UV irradiation, as well as pH value. The maximum degradation rates occurred in the initial concentration of 10 mg∙L-1 and pH value of 4, which was 53.1% and 82.6%, respectively. The addition of nitrate can promote the photodegradation of azithromycin but Fe (III)-oxalate complexes had the opposite effect. The achievements proved photodegradation is a promising technology to remove azithromycin from water environment.
