Efficient removal of norfloxacin from water using batch airlift-electrocoagulation reactor: optimization and mechanisms analysis.

ABSTRACT: In this study, we developed an airlift-electrocoagulation (AL-EC) reactor to remove norfloxacin (NOR) from water. Six parameters influencing NOR removal were investigated, and the possible removal mechanism was proposed based on flocs characterization and intermediates analysis. The performances for treating different antibiotics and removing NOR from 3 types of water were also evaluated. The best NOR removal efficiency was obtained with the iron anode and aluminum cathode combination, a current density of 2 mA cm^-2, an initial pH of 7, a treatment time of 32 minutes and an air flow rate of 200 mL min^-1, the supporting electrolyte type was NaCl, and the initial NOR concentration was 10 mg L^-1. Flocs adsorption and electrochemical oxidation were the main way
