Abstract Pollution of antibiotics in water has aroused global concerns. In this study, non-thermal discharge plasma oxidation was applied to eliminate three antibiotics with different substituent groups and chemical properties, tetracycline (TC), sulfadiazine (SD), and ciprofloxacin (CIP). All the three antibiotics could be effectively degraded but with different reaction kinetics, and the reaction rate of TC was always the highest, followed by SD and CIP. Reactive oxygen species (ROS) including O2−, 1O2, and OH all contributed to the removal of the three antibiotics. The theoretically calculation using Gaussian with DFT indicated that the ionization potential (IP) of the three antibiotics was in the order of TC
