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 …

The feasibility of using two important and common clay minerals, kaolinite and
montmorillonite, as adsorbents for removal of toxic heavy metals has been reviewed. A good …

Acid activation is a chemical treatment traditionally used on clays, typically bentonites in
hydrochloric or sulphuric acid, to obtain partly dissolved materials with enhanced surface …

An efficient material is required to develop effective removal systems with high flexibility and
low cost for capturing toxic ions. In this study, a synthesized lanthanum oxide-modified …

Heavy metal pollution in the environment and effects on human health is within the most
important issues. Because of continuous deterioration of water quality and persisting …

The ability of bentonite clay to remove Pb (II) from aqueous solutions and from nitric acid,
hydrochloric acid and perchloric acid solutions (1.0–1× 10− 5) has been studied at different …

A wide range and variety of minerals are used in the pharmaceutical industry as active
ingredients. Such minerals may be administered either orally as antacids, gastrointestinal …

The structural modifications and the Bronsted acid sites generated during the acid treatment
of montmorillonite clay with varied concentration of sulphuric acid was determined using FT …

Sorption techniques are widely used to remove heavy metal ions from large volumes of
aqueous solutions. Herein, the natural and some artificial materials, such as clay minerals …

The bentonite is a widely available and abundant natural mineral, and can be a low cost
adsorbent for water and wastewater treatment. This study reported here was directed …
