Removal of Chelated Copper by TiO2 Photocatalysis: Synergetic Mechanism Between Cu (II) and Organic Ligands
UV/TiO2 photocatalysis of chelated copper in aqueous solutions has been performed starting from Cu(II)-tartaric acid, Cu(II)-citric acid, Cu(II)-EDTA and Cu(II)-DTPA,in the presence of oxygen and at acidic pH. The photocatalytic reaction obeys first-order kinetic equation. The influence of Cu(II) on photocatalytic oxidation of organic ligands and how the various organics will affe...
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 کاملKinetics of photocatalytic degradation of methylene blue on nanostructured TiO2 coatings created by sol-gel process
Sol-gel process was chosen to produce a photocatalytic film to degrade methylene blue. In order to study structural and morphological properties of the coatings, a base sol of TTIP, I-PrOH, and DEA was prepared. Then with addition of 45g/L PEG 2000, 30g/L TiO2 and 15g/L PEG 2000 + 30g/L TiO2, to the base sol, three other sols were produced. The results of this study indica...
متن کاملTiO2 Photocatalysis and Diamond Electrode
This paper presents a simple process for making tellurium (Te) nanoand microtubes of widely varying dimensions with the multiscale processing (MSP) technique. In this process, the Te metal was placed in a borosilicate glass reaction vessel and a fuse quartz substrate was added. Th vessel was evacuated and seal d unde vacuum with a torch. Then, the vessel was heated under a temperatur gradient w...
