This study aims to investigate the treatment of real textile wastewater using a novel bentonite clay/TiO2/ZnO-based ozonation catalyst. In this study, synergic electroflocculation/catalytic ozonation, catalytic and processes are applied in modified hybrid reactor. To authors’ knowledge, is first application clay/TiO2/ZnO as an catalyst for treating wastewater. The four operational variables—ozo...

In recent years, Pillared InterLayered Clays (PILCs) have been widely used in several applications; in particular in adsorption and catalysis. The research interest in this family of solids has increased considerably. Clay minerals provide distinct nanometer-scaled layers and interlayers for engineering them as active catalysts. As such, strategic design and preparation has led to a variety of ...

Nontronites are the ferric members of dioctahedral smectites, most of which are structural counterparts of beidellite (Brindley, 1980). The existence of a cont inuous b e i d e l l i t e n o n t r o n i t e series was suggested on the basis of chemical analyses by Ross & Hendricks (1945). However, a nontronite with montmorillonitic structure has been described by KSster (1982). Minor amounts of...

Monolayer protected nanoparticles, Au@ZrO 2 @stearate and Ag@ZrO 2 @stearate, in which the core–shell nanoparticles, Au@ZrO 2 and Ag@ZrO 2 (ZrO 2 coated Au and Ag nanoparticles) are functionalized with stearic acid, have been synthesized and characterized. The air-dried powders, freely dispersible in several organic solvents (both polar and non-polar), are stable for extended periods. The mater...

To endorse sufficient water affinity to multiwalled carbon nanotubes (MWCNTs), dendritic hyperbranched poly(ether-ketone) (HPEK) was first covalently grafted to the surface of a MWCNT via a Friedel-Crafts acylation reaction. The resultant HPEK-grafted MWCNT (HPEK-g-MWCNT) was subsequently sulfonated in chlorosulfonic acid to produce sulfonated HPEK-g-MWCNT (SHPEK-g-MWCNT), which is dispersible ...

The optimization of formulation is the next task to formulate an effective rapid dispersible tablet with ideal wetting, dispersion properties to achieve rapid release profile of finished product. In preliminary work, the initial formulation was established to enhance the solubility and rapid release of Tolfenamic acid, but the optimization of size of granules and quantity of disintegrants was n...
