High efficient degradation of Cefixime using UV/TiO2 photocatalytic process: A comparison between photocatalytic and photolytic
Introduction: The existence of pharmaceuticals in aquatic ecosystem, their persistence and possible effects on living organisms and inefficient systems in removal of these compounds from water and wastewater are a growing concern. In this research, the UV/TiO2 photocatalytic degradation of Cefixime was investigated so as to identify if this method was efficient for removal of Cefixime or not. ...
متن کاملPhotocatalytic degradation of phenol in water using TiO2 and ZnO.
Photocatalytic degradation of chemical pollutants in water was investigated using semiconductor oxide catalysts, zinc oxide (ZnO) and titanium dioxide (TiO2) and phenol as the substrate. Influence of various parameters such as characteristics of the catalyst, irradiation time, substrate and catalyst concentrations, pH etc. has been studied and optimum conditions for the complete degradation of ...
متن کاملContinuous-Flow Photocatalytic Degradation of Organics Using Modified TiO2 Nanocomposites
In this study, TiO2 nanotubes (TNTs) were fabricated on a Ti sheet following the anodic oxidation method and were decorated with reduced graphene oxide (RGO), graphene oxide (GO), and bismuth (Bi) via electrodeposition. The surface morphologies, crystal structures, and compositions of the catalyst were characterized by field emission scanning electron microscopy, Auger electron spectroscopy, X-...
متن کاملUV/TiO2 photocatalytic degradation of xanthene dyes.
UV/titanium dioxide (TiO(2)) degradation of two xanthene dyes, erythrosine B (Ery) and eosin Y (Eos), was studied in a photocatalytic reactor. Photocatalysis was able to degrade 98% of Ery and 73% of Eos and led to 65% of chemical oxygen demand removal. Experiments in buffered solutions at different initial pH values reveal the pH dependence of the process, with better results obtained under ac...
متن کاملPhotocatalytic Degradation of Ibuprofen Using TiO2 and Ecotoxicological Assessment of Degradation Intermediates against Daphnia similis
Several pharmaceutical compounds have been detected in natural aqueous systems and ibuprofen (IBF), one of the most consumed medicament, has been detected in many countries. The degradation efficiency of IBF under TiO2/UV radiation was evaluated. Optimum degradation results were observed using 20 mg∙L−1 of TiO2, pH 7.8 and 5 mg∙L−1 of IBF. Under these experimental conditions total IBF removal w...
