The physicochemical properties of smectite clay minerals that determine their industrial utilization are reviewed. Smectite is the name used for a group of phyllosilicate mineral species, the most important of which are montmorillonite, beidellite, nontronite, saponite and hectorite. These and several other less common species are differentiated by variations in chemical composition involving substitutions of Al for Si in tetrahedral cation sites and Al, Fe, Mg and Li in octahedral cation sites… Expand

Basics of Clay Minerals and Their Characteristic Properties
Clay minerals such as kaolinite, smectite, chlorite, micas are main components of raw materials of clay and formed in presence of water. A large number of clays used to form the different structureExpand

Clay and clay minerals have always been used since the ancient times for making ceramic materials and also as a building material. Over the past decades, there has been a growing trend in theirExpand
Enhanced Sorption of Trichloroethene by Smectite Clay Exchanged with Cs
Trichloroethene (TCE) is one of the most common pollutants in groundwater, and Cs+ can be a cocontaminant at nuclear facilities. Smectite clays have large surface areas, are common in soils, haveExpand
Assessment of the surface areas of silica and clay in acid-leached clay materials using concepts of adsorption on heterogeneous surfaces.
TLDR
Two clays of the areas of Kaélé and Kousseri (extreme North Cameroon) containing mainly smectites and minor amounts of kaolinite were activated with sulfuric acid, and variations in adsorption energy distribution can be assigned to the presence of amorphous silica. Expand
Enhanced sorption of trichloroethene by smectite clay exchanged with Cs+.
TLDR
The results implicate enhanced retention of TCE in aquifer materials containing smectites accompanied by Cs+ cocontamination, which hypothesize can be attributed to the lower hydration energy and hence smaller hydrated radius of Cs+, which expands the lateral clay surface domains available for sorption.
