Toxicity of Organoclays to Microbial Processes and Earthworm Survival in Soils

open access: yesJournal of Hazardous Materials, 2013
Organoclays have wide spread application in environmental remediation and nanocomposites synthesis. Some of the quaternary ammonium compounds (QACs) commonly used to prepare organoclays are toxic to biota.

Cement substitution by organoclay – The role of organoclay type

Cement and Concrete Composites, 2015
Abstract In this paper three organically modified clays (OC) with different functional group of modifier and basal spacing ( d 001 ) but approximately the same alkyl chain length were considered in order to identify which parameter of OC is the most characteristic for the selection of appropriate OC for cement substitution.

The Swelling Behavior of Organoclays

Key Engineering Materials, 2007
Natural clay minerals are ideal nanofillers for polymer materials and have been attracted tremendous research and development interests in the past decade. The manufacture of clay nanofillers relies largely on the exfoliation of clay particle into individual clay platelets.

Permanent, Non-Leaching Antimicrobial Polyamide Nanocomposites Based on Organoclays Modified With a Cationic Polymer [PDF]

open access: yesMacromolecular Materials and Engineering, 2009
The intercalation of cationic copolymer into a smectic clay, montmorillonite, has been used to produce polymerically modified organoclays. The organoclays of different lamellar morphology and content of quaternary ammonium groups have been prepared by ...

Sorption of Isoxaflutole and DKN on Organoclays

Clays and Clay Minerals, 2004
AbstractSorption of the herbicide isoxaflutole and its main degradate, diketonitrile (DKN), to natural clays, SAz-1, SWy-2 and SHCa-1, and the organoclay derivatives (octadecylammonium (ODA) and hexadecyltrimethylammonium (HDTMA)) of these clays was investigated.
