Characterization and purification of Algerian natural bentonite
Introduction Bentonitic clays from the Hammam Boughrara deposit in the Maghnia area (northwestern Algeria) were studied by mineralogical, chemical and physicochemical characterization to evaluate their potential suitability as raw and purified materials in pharmaceutical and cosmetic applications. Methodology Natural bentonite This process is typically used for sodiummodification of calcium bentonite (Huang et al., 2010). Hayakawa et al.

Synthesis of environmental-friendly ion-imprinted magnetic
In the polymerization process, the template ion crosslinking functional monomer was introduced to construct the specific adsorption site of ion imprinted polymers[25]. After removing the template ions, a special cavity with a certain size and spatial configuration is left, that is, the memory effect on the target ions in water Bentonite. •. Bentonite is an absorbent natural smectite clay. It has a colloidal structure in water. Each smectite particle is composed of thousands of submicroscopic platelets stacked in a sandwich fashion with a layer of water between each. A single platelet is 1 nm thick and up to several 100 nm across.Bentonite an overview ScienceDirect Topics

Molecules Free Full-Text Valorization of Moroccan Bentonite
The main objective of this work was to contribute to the reduction in the contamination of phenolic compounds contained in margin by an adsorption process on two types of raw bentonite. The margin used in the studies was collected from a semi-modern oil mill located in the Nador–Morocco region. The results of the physico-chemical analyses Adsorption process was endothermic and feasible. The adsorption pathways of Pb 2+ on sodium bentonite are mainly including ion exchange, surface hydroxyl functional group capture, electrostatic attraction and chemical precipitation by CO 3 2-in the pore channel to form PbCO 3. This research is anticipated to give technical support for Sodium modification of low quality natural bentonite as

Modification of Bentonite with Cationic and Nonionic
Modification of bentonite with a nonionic surfactant did not cause an expansion of the interlayer space of smectite, regardless of the presence of a cationic surfactant. The modification process was found to significantly decrease the specific surface area of bentonite. Improvement of hydrophobic properties and thermal stability was also The sorption and desorption of uranium(VI) on GMZ bentonite was investigated as functions of contact time, pH, ionic strength, foreign ions, HSs and initial U(VI) using batch experiments. It is revealed that the sorption strongly depended on pH, cations (Li+, Na+ and K+) and anions (CO3 2−, SO4 2− and PO4 3−). HA benefits the Sorption and desorption of uranium(VI) on GMZ bentonite:
