Abstract

Ofloxacin (OFX) is a third-generation fluoroquinolone antibiotic widely used to treat respiratory diseases and infections. Due to improper discharge treatment, it can be detected in a variety of aquatic environments such as pharmaceutical wastewater and surface water. In addition, ofloxacin is not easily biodegradable, has toxic effects on aquatic organisms and crops, and cannot be fully removed by conventional treatment. Therefore, it is an important research topic to find effective ways to degrade ofloxacin and reduce its harm to human body and environment. Photocatalysis is a technology that uses solar energy to convert light energy into chemical energy, which can effectively remove refractory organic matter in water environment. The single photocatalytic technology has the problems of low conversion of light energy and slow reaction rate, but the photocatalytic technology can reduce the photogenerated carrier recombination by introducing an external electric field, so as to improve the energy utilization rate and reaction rate. In this paper, Ti/SnO₂-Sb (TSSA) electrode material coupled particle electrode was used to realize the treatment of ofloxacin in wastewater containing antibiotics, and the introduction of particle electrode into photoelectric catalysis was explored, and the coupling system was constructed to enhance its catalytic performance.
