Optimization of photo-degradation of direct blue 258 using nano Titanium Oxide with response surface method
The photodegradation of Direct Blue 258, a member of the group of azo dyes which are commonly used in the various branches of the industry, was studied. The photostability of this dye was not previously surveyed. Photocatalytic degradation method was evaluated. The both light source include solar simulated (UV 400 W lamp) and sun light (E= 400 W/m2) and titanium dioxide nanoparticles were used ...

متن کاملTiO2 photocatalysis
It is known that TiO2 exhibits good photocatalytic properties which could be used in various commercial applications such as water and air purification or photo-induced biodegradation of microbes. TiO2 occurs in nature in the form of three crystal polymorphs: anatase, brookite and rutile. For photocatalytic applications only anatase and rutile are of interest, however anatase shows greater phot...
متن کاملPhotocatalytic degradation of E. coli bacteria using TiO2/SiO2 nanoparticles with photodeposited platinum
In this work, TiO2 /SiO2 (pure anatase), and TiO2 /SiO2 (anatase/rutile) nano-photocatalysts are prepared by using sol-gel method and control of acidity. The particles size is calculated using Scheerer, s equation and is estimated to be around 7-15 nm. In order to improve the photocatalytic activity of TiO2 /SiO2 ,1% (wt) platinum particles are loaded on both catalysts using photoreductive meth...
متن کاملDegradation of the antibiotic oxolinic acid by photocatalysis with TiO2 in suspension.
In the work presented here, a photocatalytic system using titanium Degussa P-25 in suspension was used to evaluate the degradation of 20mg L(-1) of antibiotic oxolinic acid (OA). The effects of catalyst load (0.2-1.5 g L(-1)) and pH (7.5-11) were evaluated and optimized using the surface response methodology and the Pareto diagram. In the range of variables studied, low pH values and 1.0 g L(-1...
