OPTIMISED PHOTOCATALYTIC DEGRADATION OF CIPROFLOXACIN USING METAL-DOPED TITANIUM DIOXIDE NANOPARTICLES

Abstract

This flat display shaped by ciprofloxacin pharmaceuticals among water sources remains a potential threat to the ecosystems aversive to environmental and health effects save for decommissioning. This research focuses on determining the enhanced photocatalytic removal of ciprofloxacin through metal-doped TiO2 nanocomposite particles. Several metal dopants such as, silver, iron and copper metal ions were investigated on the visible light photocatalytic activity of TiO2. Thus, parameters of the influences on which the reaction rate allows for the optimisation of experimental conditions, namely pH level, the dosage of a catalyst, and the initial concentration of ciprofloxacin were comprehensively investigated. In these experiments, the enhancement of degradation efficiency has clearly shown that the metal-doped TiO2 nanoparticles are more efficient in the degradation process; here the highest degradation rate is achieved by Ag-doped TiO2. Pseudo-first-order kinetic analysis of the data further substantiated the above observation. Hence this research reveals the possibility of using metal-doped TiO2 nanoparticles for efficient wastewater treatment.
