Plants are exposed to diverse abiotic stresses like drought, heat, salinity, and high-metal
concentrations at different stages of their life cycle. As protection against stress, plants …

Montmorillonite− copper oxide (MMT-CuO) nanocomposites were prepared by a facile and
eco-friendly method and introduced into chitosan (Cs) matrix to enhance its optical …

Layer charge reduction of selected homoionic swelling clay minerals upon heating is
reviewed. This phenomenon is known for Li+-montmorillonites as the Hofmann-Klemen …

Adsorption/desorption and oxidation/reduction of arsenic at clay surfaces are very important
to the natural attenuation of arsenic in the subsurface environment. Although numerous …

A series of activated palygorskite clay by HCl with different concentrations was prepared and
applied as adsorbents for removal of Cu (II) from aqueous solutions. The effects of contact …

X-ray powder diffraction (XRPD) analysis demonstrated that the main montmorillonite
component of Unye bentonite was more effective in the Pb2+, Cu2+, Ni2+, Co2+, Zn2+, Al3+ …

Background: 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 …

Calcium montmorillonite (Ca-MMT), sodium montmorillonite (Na-MMT) and acid-activated
montmorillonite (AAM), and their Cu2+-exchanged montmorillonites (Cu-MMT), Cu* Ca …

The aim of this study is to determine the effect of the layer charge of smectites on their
electrophoretic mobility (EM), using electrophoresis measurements. In order to cover the …

Interaction between metal Fe and a variety of natural and synthetic smectite samples with
contrasting crystal chemistry was studied by scanning electron microscopy and X-ray …
