Heterogeneos Photocatalytic Decolorization of Brown NG by TiO2 –UV Process
The photocatalytic decolorization of aqueous solutions Brown NG, a commercial textile dye, was studied using titana Degussa P-25 as a catalyst for the first time. The experiments were carried out in a batch reactor with the use of artificial light sources (UV-C). The effects of various process variables on decolorization performance of the process have been investigated. The photodegradatio...
متن کاملDecolorization of a Reactive Dye by UV-Enhanced Ozonation
In the present study the treatment efficiency of O3 and UV+O3 processes were compared for the oxidation of simulated dyebath effluent containing a mixture of a reactive dye (C.I. Reactive Blue 19) and various dye auxiliary chemicals. The color, COD and TOC removal rates were assessed for different processes. The effect of initial dye concentration and presence of sodium hydroxide and sodium car...

متن کاملHigh 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 Decolorization of Uranine Using UV/S2O8 and UV/H2O2 Processes from Aqueous Solutions: A Laboratory Study
Background and Objectives: The entry of textile mills’ wastewater into the environment causes severe disruption to aquatic environments. Thus, the aim of this study was to compare the performance of processes of UV/ S2O8 and UV/H2O2 in removal of Uranine dye from aqueous solutions. Materials and Methods: In this laboratory study, in a batch reactor, the efficiency of UV/S2O8 and UV/H2O2 photoc...
