Description
Summary:Results presented in this paper are pioneering attempt toward better understanding of the thermal stability of acetochlor sorption in inorganic and organic montmorillonites. Changes in surface properties of acetochlor adsorbed on montmorillonites and montmorillonites modified with hexadecyltrimethylammonium bromide have been investigated by thermogravimetry, derivative thermogravimetry and infrared spectroscopy. The mass loss, as a result of the heating treatment, indicates release of free water, transformation of hydrophilic to hydrophobic surface, the release of acetochlor sorbed on the montmorillonite, the release of acetochlor sorbed on the montmorillonite and dehydroxylation of the structural OH units.
