Electrochemical mineralization of cephalexin using a conductive diamond anode: A mechanistic and toxicity investigation.

The contamination of surface and ground water by antibiotics is of significant importance due to their potential chronic toxic effects to the aquatic and human lives. Thus, in this work, the electrochemical oxidation of cephalexin (CEX) was carried out in a one compartment filter-press flow cell using a boron-doped diamond (BDD) electrode as anode. During the electrolysis, the investigated variables were: supporting electrolyte (NaSO, NaCl, NaNO, and NaCO) at constant ionic strength (0.
