Effect of methylene blue on the disposition of ethanol.

Photocatalytic outcomes for methylene blue degradation from CTAB mediated mesoporous ZnS, synthesized with an insoluble precursor in ethanol media

The aim of the present study is to demonstrate how mesoporous nanostructures of Zinc Sulfide (ZnS) will precipitate in an ethanol media in spite of negligible solubility of Sodium Nitrate (Na2S), which is role-played as sulfur precursor. On the following, the role of such synthesizing method on the photocatalytic behavior of ZnS mesoporous nanostructures has been investigated. Characterization ...

Effect of activation factors on adsorption of cationic dye, methylene blue, by activated bentonite

The aim of this investigation was to study the relationship between activation factors and adsorption of cationic dye, methylene blue MB, by activated bentonite. The adsorption index was investigated as a function of acid type, time and temperature. A commercial bentonite was selected as a starting material and the effect of heat treatment on MB adsorption were determined in a batch setup. Thou...

Investigation of performance of bimodal/functionalized mesoprorous silica nanoparticles on the adsorption of methylene blue from aqueous solution

In this study, bimodal mesoporous silica, i.e. UVM-7, was synthesized and functionalized withsulfonic acid and characterized using XRD, nitrogen physisorption, SEM, TEM and acid/basetitration. The results displayed that bimodal mesopore structure was firmly formed and acidicfunctional groups were grafted on the surface of the UVM-7. The concentration of the acidicfunctional groups was determine...

Kinetics 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...
