Preliminary experiments on ciprofloxacin degradation via TIO2 assisted photo catalyse

Abstract

Ciprofloxacin (CIP) is an intensively used antibiotic, which led to the development of bacterial resistance in water. Therefore, both ciprofloxacin and ciprofloxacin-resistant bacteria are emerging concerns that can threaten human health. CIP photo catalyse was studied in the last period for various newly synthesized catalysts and experimental results proved that CIP photocatalytic degradation represents a promising method for CIP removal from aqueous systems. The results on role of various active species for photocatalytic degradation of CIP are contradictory. Some researchers are stating that hydroxyl radicals and holes play the major role and others are attributing the major role to superoxide radicals formed by electrons and oxygen. Therefore, there is a need for more investigations on CIP photocatalytic degradation.
