The presence of tetracycline together with other antibiotics even at micrograms per liter concentrations in natural aqueous
environments may induce chronic toxic effects in aquatic plants and microorganisms. For instance, chronic exposure of bacteria and other microorganism to antibiotics may cause the development of antibiotic resistance in the environment, which may threaten our ecosystem [5]. Therefore, it is of great importance to develop cost-effective treatment technologies to remove such compound from aqueous solutions.
