Removal of methylene blue dye aqueous solution using photocatalysis
The nano sized TiO2 and ZnO are the most active photocatalysts. Methylene blue was used as a reference molecule for the photocatalytic degradation. The TiO2 and ZnO can totally remove methylene blue dye. The effect of various process parameters like initial concentration, contact time, dose of catalyst and pH on the extent of removal of dye by photocatalysis in presence o...

متن کاملEfficient Fenton like degradation of Methylene blue in aqueous solution by using Fe3O4 nanoparticles as catalyst
Fe3O4 nanoparticles were prepared hydrothermally and characterized by X-Ray diffraction spectroscopy (XRD), and scanning electron microscopy (SEM). It was found that these nanoparticles can act as an efficient catalyst in the degradation of Methylene blue dye in aqueous solution in a Fenton like system in presence of 30% perhydrol. Uv-Vis spectroscopy was used to determine the concentration of ...
متن کاملEfficient Removal of Methylene Blue by Fenton-like Reaction using nZVI/GAC Composite as Catalyst
A composite of nano-zerovalent iron (nZVI) supported on granular activated carbon (GAC) was synthesizedthrough adsorption-reduction method, and its performances used as catalyst of Fenton-like were investigated to degrade methylene blue (MB) in model wastewater.Theresults show thathomogeneous dispersion of nZVI was greatly improved after supported on GAC. In comparison, the composite (nZVI/GAC)...
متن کاملDecolorization of Methylene Blue from Aqueous Solution Using Ultrasonic / Fenton Like Process (RESEARCH NOTE)
Docolorization of Methylene Blue was investigating using a Ultrasonic/Fenton like reactor in batch mode. The effects of pH, reaction time, initial concentration of dye, H2O2 and Fe on the dye removal was studied. It was found that the increase of initial dye and H2O2 concentration and the increase of initial pH, are not beneficial for improving the dye removal efficiency. Increasing the dye con...
