Application of electrolysis to inactivation of antibacterials in clinical use

► Contamination of surface water with antibacterials may induce drug resistant bacteria. ► We examined if the electrolysis capable to inactivate 10 groups of antibacterials. ► Electrolysis was able to inactivate almost all antibacterials and the mixture. ► Cytotoxicity was not detected in any of the electrolyzed solutions. ► Electrolysis is considered to be applicable to treat hospital wastewater.
