Abstract: In recent years the increasing use of pharmaceuticals and personal-care products (PPCPs), especially antibiotics, has become a particular concern because of their undesirable potential ecological and human health effects. A large part of the antibiotics consumed ends up in wastewater, and in the wastewater the antibiotics may exert selective pressure for or maintain resistance among microorganisms. This study aimed to survey a total four common human and veterinary antibiotics, including amoxicillin, Penicillin, Cephalexin, and Azithromycin based on SPE-LC-MS-MS technology in a wastewater treatment plant at one of equipped wastewater treatment plant (WWTP) in Isfahan province. Samples were taken from the influent and effluent of a WWTP. The samples were prepared using solid-phase extraction (SPE). Also some antibiotics removal methods reviewed that these methods can be put into practice in Iran. In conclusion, It can be said except Azithromycin, other antibiotics were detected in the input and output of WWTP and perhaps after passing through various stages of WWTP, their concentration were low or may exert selective pressure for or maintain resistance among microorganisms and Azithromycin, not detected in input and output of WWPT. Also in Compare of methods together, can be said that ACs, for eliminating of important most used antibiotics in Iran, (amoxicillin and cephalexin) is a good choice and has a high removal efficiency and easier Operating condition than other methods. By usage of ACs method in WWTPs, we can prevent the entry of antibiotics in the environment and water resources in Iran.
