Abstract：In order to understand the photochemical process of antibiotics in aquatic environment and evaluate their ecological risk accurately, the influences of tylosin initial concentration, pH, ionic strength, and humic acid on the photodegradation of tylosin by goethite were investigated. The results showed that the photodegradation rate of tylosin was proportional to solution pH and inversely proportional to tylosin initial concentration and ionic strength. The humic acid could promote the photodegradation of tylosin on goethite. The photodegradation of tylosin on goethite might include the homogeneous reaction in the solution and the heterogeneous reaction at goethite surface.
