Adsorption of terpenic compounds onto organo-palygorskite

Environmental Science and Pollution Research, 2017
Essential oils from aromatic plants are currently mentioned as suitable tools for excellent protection of stored grains from insect pest attacks. The present work aimed to study the processes of the synthesis insecticidal formulation with clay. The active terpenic compounds of essential oil of Eucalyptus globulus (Eg) were fixed in the palygorskite by ...

Adsorption of the herbicide 2,4-D on organo-palygorskite [PDF]

Applied Clay Science, 2010
Among the clay minerals, montmorillonite is the most extensively studied material using as adsorbents, but palygorskite and its organically modified products have been least explored for their potential use in contaminated water remediation. In this study, an Australian palygorskite was modified with cationic surfactants octadecyl trimethylammonium ...

Morphology and interaction of nanocomposite foams formed with organo-palygorskite and ethylene-vinyl acetate copolymers [PDF]

Polymer Bulletin, 2016
To obtain excellent mechanical properties of polymer nanocomposite foams without sacrificing the lower density through popular and friendly means. Organically modified palygorskite (OPal) was prepared with γ-aminopropyltriethoxysilane on the surface of rod-shaped Pal particles, and nanocomposite foams based on ethylene-vinyl acetate (EVA) copolymer was

Structures and properties characterization of acrylonitrilebutadiene-styrene/organo-palygorskite clay composites

Journal of Wuhan University of Technology-Mater. Sci. Ed., 2012
Palygorskite (PGS) and vinyl tris-(2-methoxyethoxy) silane (KH-172) modified palygorskite (OPGS) were used to prepare acrylonitrile-butadiene-styrene (ABS)/clay composites. Thermal stability of the composites was evaluated by using thermogravimetric analysis (TGA).

Preparation and characterization of an organo-palygorskite-Fe3O4 nanomaterial for removal of anionic dyes from wastewater

Applied Clay Science, 2017
Abstract The organophilization of clays to increase interfacial interactions is a typical practice when the objective is its encapsulation with a polymer. This work intend to synthesize and characterize an organo-palygorskite-Fe3O4, to change the hydrophilicity of the material and investigate its efficiency in the removal of two anionic dyes from ...

Influences of surfactants on the structures and properties of organo-palygorskite in oil-based drilling fluids

Microporous and Mesoporous Materials, 2017
Abstract Organo-palygorskite (OPal) is a potential rheological additive in oil-based drilling fluids. This work aims to reveal the influences of surfactants on the structures and properties of OPal in oil-based drilling fluids. Firstly, palygorskite was organically modified by three quaternary ammonium salts with different lipophilicity.

Synthesis, Characterization and Swelling Behaviour of Poly(sodium acrylate)/Palygorskite Superabsorbent Composites based on Palygorskite and Organo-palygorskite

Journal of Polymer Engineering, 2009
Novel superabsorbent composites based on partially neutralized acrylic acid (SA) and palygorskite (PLG) were synthesized by aqueous solution polymerization. The effects of PLG, organo-PLG (O-PLG) and the content of PLG in the copolymeric gels on the water sorption and the initial swelling rate in deionized water and saline solution (0.2 wt% NaCl (aq) )

Adsorption of Glyphosate by Palygorskite [PDF]

Materials Research, 2023
Glyphosate affects ecosystems due to exposure of non-target crops and is a persistent contaminant at low concentrations. The application of palygorskite to reduce glyphosate contamination in Brazil is an environmentally friendly way to remediate impacted
