Montmorillonite is an important layered phyllosilicate material with many useful physicochemical and mechanical properties, which widely used in medicine, environmental protection, construction industry, other fields. In order to a get better understanding of the behavior montmorillonite under high pressure, we studied its atomic structure, electronic properties using density functional theory ...

Natural nanomaterial; Montmorillonite Clay was collected and purified and then applied in the removal of Fluoride. The Montmorillonite Clay was grounded and 150g was weighed and refluxed in 500mL 1MHCl at 1200C for one hour thirty minutes and activated Montmorillonite Clay was obtained. Flouride was determined with the aid of SPADNS Reagent (2-parasulfophenylazo)-1,8-dihydroxy-3,6-naphthalene d...

The negative electrical field around clay particles whose edge thickness is small relative to the Debye length of the diffuse double layer associated with the planar surfaces may spill over into the edge region. Such a spillover may affect B adsorption by the clay. This study was conducted to determine the effect of edge surface properties of 2:1 clay on B adsorption. Pyrophyllite, which shows ...

SUMMARY Clays are ubiquitously located in the Earth’s near surface and have a high impact on subsurface permeability. Most geo-electrical characterizations of clays do not take into account heterogeneous nature clay geological media. We want to better understand influence heterogeneities signature, thus we collected data set spectral induced polarization (SIP) artificial non-consolidated sample...

Abstract Magnetic-clay (MtMag) and magnetic-organoclay (O100MtMag) nanocomposites were synthesized, characterized evaluated for arsenic adsorption. Batch adsorption experiments performed varying pH conditions initial As(V) concentration, while successive cycles made in order to evaluate the materials reuse. The highest removal efficiency (9 ± 1 mg g?1 7.8 ± 0.8 mg g?1 MtMag O100MtMag, respectiv...

conducting polymers, because of their special properties, are used to introduce conductive polymeric composites. also, clays have recently been used for preparation of polymer composites with enhanced mechanical and thermal properties. the aim of this work is to study the synergetic effect of the co-presence of conducting polyaniline and montmorillonite in the polyethylene matrix. polyethylene ...

background: nowadays, extensive technological advancements have made it possible to use nanopaints which show exciting properties. in ir iran excessive radon levels (up to 3700 bq m–3) have been reported in homes located in radon prone areas. over the past decades, concerns have been raised about the risk posed by resi- dential radon exposure. objective: this study aims at investigating the eff...

A method for preparing and observing clay platelets for size and shape analysis using scanning electron microscopy (SEM) was developed. Samples of the clay platelets were prepared by polyelectrolyte-assisted adsorption onto a pyrolytic graphite surface. The use of graphite as a substrate was advantageous because of the low number of secondary electrons emitted from it during imaging by SEM. The...
