    Fund Project:
  • The thermal degradation process and mechanism of three representative antibiotics, ciprofloxacin, oxytetracycline and sulfamethazine were studied with the help of thermogravimetric analysis method. The pyrolysis kinetics characteristics were analyzed by thermogravimetry. Results showed that the main pyrolysis temperature ranges of CIP, OTC and SM2 were from 150 to 625℃, 220 to 600℃ and 260 to 480℃. Their initial decomposition and weightlessness peak temperature were in the same order:OTC -1,which suggested that OTC was the easiest to be pyrolyzed. Those conclusions mentioned above provide a theory basis for eliminating antibiotics completely in sludge by the process of pyrolysis and carbonization.
