The ability of four different clays to adsorb diethylketone was investigated in batch experiments aiming to treat wastewater with low solvent concentrations. The adsorption performance in terms of uptake followed the sequence: vermiculite>sepiolite=kaolinite=bentonite, for all the adsorbent doses tested (from 0.1 to 1.5 g) in 150 mL of ketone solution (800 mg/L). The equilibrium data in the bat...

Microscopic and spectroscopic analyses were conducted on steel/bentonite interface samples removed from four in situ experiments that carried out three underground research laboratories at different temperatures under hydraulic geochemical conditions. The results provide valuable information about the corrosion processes occurring high-level radioactive waste repositories. Systematic patterns c...

The current investigation deals with the fabrication of two various composite-based bentonite clay minerals. characterization and radiation shielding parameters for fabricated composites (calcinated ball-milled calcinated bentonite) were studied. X-ray diffraction was utilized to illustrate crystalline phase composites. Furthermore, Williamson Hall’s method used determine grain size both partic...

We study the fingering instability that occurs at the contact line of a thin sheet of a yield-stress fluid flowing down an incline. We derive an expression for the wavelength of the finger pattern as a function of inclination angle for a Herschel-Bulkley fluid. The wavelength is predicted to diverge at a finite angle which is related to the yield stress of the fluid. We also measure the wavelen...

Immobilizing of zero-valent iron in mono- and bi-metallic systems on the bentonite clay surface as new nanocatalyst were synthesized and used to degrade model acidic dyes from aqueous media. The Fourier-transform infrared spectroscopy, scanning electron microscopy-energy dispersive X-ray spectroscopy, transmission electron microscopy, X-ray diffraction, and Brunauer-Emmett-Teller analysis were ...

The cement–clay interaction (CI) experiment was carried out at the Mont Terri rock laboratory to complement current knowledge on influence that cementitious materials have Opalinus Clay (OPA) and bentonite (MX). Drill cores including interface of OPA, concrete (LAC = low-alkali binder, OPC ordinary Portland cement), MX, which interacted for 4.9 10 years, were successfully retrieved after drilli...

utilizing natural clay in the traditional production of the grape concentrates in the villages cause the input of large amounts of some metals (solutes) in the product which will be harmful for the consumers. to eliminate the natural clay from this procedure in non-industrial scale, bentonite was selected as an aid-clarifier and examined in treatments under these conditions: two levels of bento...

Animal feeding studies have demonstrated that clay additives, such as bentonites, can bind aflatoxins in ingested feed and reduce or eliminate the toxicity. Bentonite deposits are found throughout the world and mostly consist of expandable smectite minerals, such as montmorillonite. The surfaces of smectite minerals can be treated with organic compounds to create surface-modified clays that mor...

Different compositions of mixtures sand and clay with medium-grade bentonite for molding critical large parts a freight car bogie are examined in the article. to improve bentonite’s physical mechanical properties, such as gas permeability compressive strength addition soda ash, considered. As material study were taken quartz grade 1K2O2025, medium Navbaharskogo birthplace, improving properties ...

Artificial neural networks (ANNs) are a new type of information processing system based on modeling the neural system of human brain. The prediction of swell pressures from easily determined soil properties, namely, initial dry density, initial water content, and plasticity index, have been investigated by using artificial neural networks. The results of the constant volume swell tests in oedom...
