Adsorption of Cr(VI) in Aqueous Solution Using a Surfactant-Modified Bentonite

open access: yesThe Scientific World Journal, 2020
Clay minerals can be modified organically by a cationic surfactant resulting in materials known as organoclays. The organoclays have been used as adsorbents of most of the organic contaminants in the aqueous solution and oxyanions of the heavy metal.

Hydraulic Conductivity of Organoclay and Organoclay-Sand Mixtures to Fuels and Organic Liquids

open access: yesJournal of Geotechnical and Geoenvironmental Engineering, 2015
Abstract Hydraulic conductivity, swelling, and liquid sorption capacity (i.e., maximum organic liquid mass bound per mass organoclay solid) were measured for an organoclay with dimethylammonium bound to the surface. Five fuels (No. 1 fuel oil, No. 2 fuel oil, diesel, jet fuel, and gasoline), four pure organic liquids (methanol, phenol, ethylbenzene ...

Dendrimers-containing organoclays: Characterisation and interaction with methylene blue

open access: yes, 2017
International audienceThe structure of organoclays composed of synthesized phosphorus-based dendrimers, which was endowed with peripheral ammonium groups, and stevensite- or montmorillonite-rich clays was examined using X-ray diffraction, high resolution

Interactions of acidic herbicides bentazon and dicamba with organoclays

open access: yes, 2012
We determined the sorption mechanism of the acidic herbicides bentazon [3-(1-methylethyl)-1H-2,1,3-benzothiadiazin-4(3H)-one 2,2-dioxide] and dicamba (3,6-dichloro-2-methoxybenzoic acid) on two organoclays, octadecylammonium (ODA)- and ...

Effects of inorganic fillers on the extensional rheological and morphological properties of polylactic acid/low-density polyethylene blends

open access: yesPolymer Testing
Polylactic acid (PLA)/low-density polyethylene (LDPE) blends filled with hydrophilic and hydrophobic fumed silica or organoclays were characterized by linear viscoelastic (LVE) and extensional properties.
