研究成果概要

Organoclays (e.g. clay minerals modified by surfactants) are hybrid layered materials combining a hydrophobic surface and a large interlayer space. Those materials can be used with success as adsorbents for the removal of various types of organic pollutants, including hydrophobic ones such as emerging pollutants (pharmaceuticals, pesticides, herbicides…). However, the final adsorption properties of organoclays mainly depend on the type of surfactants associated with the clay mineral, as well as its loadings and/or organization. The association of a clay mineral (montmorillonite) with several nonionic surfactants of different moieties was studied and their adsorption properties was studied by focusing on recalcitrant herbicides of diverse hydrophilic lipophilic balance. By showing a dual display hydrophilic and hydrophobic surface, the nonionic organoclays (e. g. organoclays prepared with nonionic surfactants) appear as versatile adsorbents for the whole studied herbicides.
