Abstract The composition of Rhassoul clay is controversial regarding the nature pure-mineral fraction which claimed to be stevensite rather than saponite. In this study, raw and mineral fractions were characterized using various techniques including Fourier transform infrared spectroscopy magic angle spinning nuclear magnetic resonance (MAS NMR). isolated fine contained a larger amount Al (>1 wt.%) that reported for other occurrences. 27 MAS NMR technique confirmed in equally split...
This study aims at understanding the effect of different heat treatments on evolution microstructure several Cr–W–V–Mo steels having compositions and how this latter affects their abrasion resistance. The investigation also gives insights formation core-shell carbides commercial highly alloyed stainless steel HCx® six newly designed were subjected to three treatments: austenitizing 900 °C 1100 subsequent quenching, an ageing treatment 700 °C. microstructural analysis demonstrated Laves phase...
The exploitation of beidellite clay (BDT), used as a nanofiller in the preparation poly(butylene succinate) (PBS)/organoclay biodegradable nanocomposites, was investigated. A series bionanocomposites with various loadings organoclay (3CTA-BDT) were prepared by situ polycondensation reaction between succinic anhydride (SuAh) and 1,4-butanediol (1,4-BD) at atmospheric pressure refluxing decalin azeotropic removal water, catalyzed non-toxic bismuth chloride (BiCl3). X-ray diffraction (XRD)...
This study deals with the influence of physicochemical parameters, namely, photocatalyst loading, dye concentration, and pH polluted solutions, on degradation efficiency Orange G (OG) solutions containing TiO 2 nanoparticles supported palygorskite clay mineral (TiO -Pal). The attached to natural fibers was elaborated by colloidal sol-gel route. It exhibits anatase structure that is most photoactive crystallographic form. highest performances OG were found using an optimum amount -Pal around...
Abstract The Maastrichtian-Palaeogene series of the Western High Atlas and Meseta Basins in Morocco are particularly rich palygorskite. present work is aimed at clarifying genesis palygorskite from interbedded facies gaining an understanding their relationships with depositional environment. mineralogical characteristics these were studied by X-ray diffraction (XRD) electron microscopy (SEM/TEM). content microstructure show large geographical stratigraphical variations deposits studied....
Abstract TiO 2 /stevensite nanocomposite photocatalysts were synthesized by a solvothermal method using TiCl3/HCl as reactants and the stevensite clay mineral extract support. The prepared photocatalyst samples then characterized various techniques such X-ray diffraction (XRD), Infrared spectroscopy (IR) Transmission Electron Microscopy (TEM). Points of Zero Charge (PZC) evaluated titration non-modified Ti-modified aqueous dispersions, with cationic surfactant solutions. photocatalytic...
Sulfate-modified Ag 2 CO 3 was successfully synthesized via a simple precipitation method. Its visible light photocatalytic performance against the removal of Orange G found to be significantly enhanced in comparison with one pure .
