AB  - The extensive use of antibiotics has led to their presence in the aquatic 
      environment, and introduces potential impacts on human and ecological health. The 
      capability of powdered activated carbon (PAC) to remove six frequently used 
      quinolone (QN) antibiotics during water treatment was evaluated to improve 
      drinking water safety. The kinetics of QN adsorption by PAC was best described by 
      a pseudo second-order equation, and the adsorption capacity was well described by 
      the Freundlich isotherm equation. Isotherms measured at different pH showed that 
      hydrophobic interaction, electrostatic interaction, and pi-pi dispersion force were 
      the main mechanisms for adsorption of QNs by PAC. A pH-dependent isotherm model 
      based on the Freundlich equation was developed to predict the adsorption capacity 
      of QNs by PAC at different pH values. This model had excellent prediction 
      capabilities under different laboratory scenarios. Small relative standard 
      derivations (RSDs), i.e., 0.59%-0.92% for ciprofloxacin and 0.09%-3.89% for 
      enrofloxacin, were observed for equilibrium concentrations above the 0.3mg/L 
      level. The RSDs increased to 11.9% for ciprofloxacin and 32.1% for enrofloxacin 
      at mug/L equilibrium levels, which is still acceptable. This model could be 
      applied to predict the adsorption of other chemicals having different ionized 
      forms.
