Prefabricated Bentonite Clay Liners
Geotextiles and Geomembranes, 1991Abstract The development and use of prefabricated bentonite clay liners is a relatively recent development, even for a technology as young as geosynthetics. There are four currently available commercial products, each of which consists of essentially dry bentonite clay agglomerates (with or without a dry, but water soluble, adhesive) placed on a ...

Role of bentonite clays on cell growth
Chemosphere, 2016Bentonites, naturally occurring clays, are produced industrially because of their adsorbent capacity but little is known about their effects on human health. This manuscript reports on the effect of bentonites on cell growth behaviour. Bentonites collected from India (Bent-India), Hungary (Bent-Hungary), Argentina (Bent-Argentina), and Indonesia (Bent ...

Sorption of Anthocyanins on Bentonite Clay
Russian Journal of Physical Chemistry A, 2020Patterns of the static sorption of anthocyanins on bentonite clay are determined. It is found that the approach used for static sorption is an alternative to dynamic solid phase purification on DIAPAK C18 concentrating cartridges. A way of determining the relative sorption capacity of anthocyanins characterized by different structures on bentonite clay

Diffusion of Water in Bentonite Clay
Journal of the Physical Society of Japan, 2013Diffusion of water confined in sodium bentonite clay is studied using the quasi-elastic neutron scattering (QENS) technique. Hydration of bentonite clay is characterized by several methods including X-ray diffraction and thermogravimetric measurements.

Bentonite Clays for Therapeutic Purposes and Biomaterial Design
Current Pharmaceutical Design, 2020Background:Bentonite is a natural clay composed mainly of montmorillonite with other associated minerals such as feldspar, calcite and quartz. Owing to its high cation exchange, large surface area and ability to form thixotropic gels with water and to absorb large quantities of gas, it presents a large medicinal application.Objective:This review ...

Hydration studies of Bentonite clay
AIP Conference Proceedings, 2012Bentonite clay when hydrated increases its volume several fold to form a pliable mass. X-ray diffraction showed that as hydration increases, the crystalline peaks due to kaolinite, calcite and quartz are gradually replaced by an amorphous background while the crystalline reflections of montmorillonite remain.

Influence of Bentonite Clay in the Formation of Polypropylene / Clay Nanocomposites
Materials Science Forum, 2012Based on recent studies this research aims to continue the studies on nanocomposites obtained by blending polypropylene (polymer matrix) and bentonite clays of Paraíba, with emphasis on issues related to the surface modification of clays (charges), with the aim of stimulating the compatibility between the inorganic and organic components, since after ...
