Photoelectrochemical Degradation Of Amoxicillin Using BiVO4 as Photoactive Material

The widespread use of antibiotics, pesticides and other organic pharmaceuticals results in its accumulation in the aquatic environment as they are regularly detected in surface and waste waters. Environmental policies regarding the quality of discharged wastewater are tightening ; demanding new solutions for water treatment in all water intensive industries as well as municipal wastewater. Among the antibiotics, amoxicillin is one of the frequently used ones. Since its impact on human health and the environment is uncertain it is considered an emerging contaminant. Wastewater treatment plants do not remove amoxicillin efficiently, which contributes to its presence in drinking water and water bodies. In order to decompose organic contaminants in an aquatic system, photoelectrochemical processes might be employed. In this work, photoelectrochemical (PEC) degradation of amoxicillin was investigated using BiVO4 as a solar light activated material. The photoactive material was deposited onto FTO glass electrodes and characterized using various electrochemical methods including linear sweep voltammetry (LSV) and electrochemical impedance spectroscopy (EIS). Moreover, the effect of combining BiVO4 and reduced graphene oxide (rGO) in PEC degradation of amoxicillin was studied.
