Natural and synthetic clays have been used as adsorbents for removal of heavy metals and
dyes from aqueous solution for many decades. In the last decade, exfoliating the natural …

Clay minerals retain or adsorb metal ions in the Earth's critical zone. Rocks, sediments and
soils rich in clay minerals can concentrate rare earth elements (REEs) in ion adsorption-type …

This review discusses the recent trends in the research over the last 30 years to use clay
minerals in natural and modified forms for removing different toxic organic/inorganic …

Clay minerals and their modified derivatives have composed a large family of adsorbents
which can be used for the adsorption of most of the chemical contaminants from aqueous …

Although clay minerals play fundamental roles in many environmental processes, especially
in controlling the movement of various ions and molecules in soils, they are also useful …

Many chemical compositions produce layered solids consisting of extended sheets with
thickness not greater than a few nanometers. The layers are weakly bonded together in a …

Among the wide range of materials used for remediating environmental contaminants,
modified and functionalised nanoclays show particular promise as advanced sorbents …

Pillared clays are special kinds of modified clays with significant and permanent porosity,
produced by embedding columns or pillars between the layers of clay. However, these …

The use of pillared interlayered clays (PILCs) as heterogenous catalysts in wastewater
treatment technologies, particularly advanced oxidation processes (AOPs), is gaining …

Sulfur hexafluoride (SF 6) is an industrial gas used in various applications such as high-
voltage electrical transmission and distribution systems, film protection, semiconductors, and …
