Functionalization of Bentonite by Intercalation of Surfactants
The functionalization of bentonite by intercalation of surfactants dodecylamine, hexadecylamine, octadecylamine, and the octadecyltrimethylammonium cation is described. Products are characterized by elemental analysis, thermal analysis, FT–IR spectra, and powder X-ray diffraction analysis. Laminar amine-clay nanocomposites contain about one mol amine per (Si,Al)4 clay unit, while the cationic s...
متن کاملAdsorption Removal of Humic Acid from Water Using a Modified Algerian Bentonite
In this study, the main objective is the preparation and the characterization of a modified Algerian bentonite based adsorbent by intercalation with hexadecyltrimethylammonium bromide (HDTMA). Natural and modified bentonites were characterized using thermogravimetric analysis (TGA), X-ray diffraction (XRD) and infrared spectroscopy (FTIR). The X-ray results indicate that the geometry of the int...
متن کاملMicroorganism-mediated synthesis of chemically difficult-to-synthesize Au nanohorns with excellent optical properties in the presence of hexadecyltrimethylammonium chloride.
Closely packed, size-controllable and stable Au nanohorns (AuNHs) that are difficult to synthesize through pure chemical reduction are facilely synthesized using a microorganism-mediated method in the presence of hexadecyltrimethylammonium chloride (CTAC). The results showed that the size of the as-synthesized AuNHs could be tuned by adjusting the dosage of the Pichia pastoris cells (PPCs). The...
متن کاملThe effect of surface topography on the micellisation of hexadecyltrimethylammonium chloride at the silicon-aqueous interface.
Amphiphilic aggregation at solid-liquid interfaces can generate mesostructured micelles that can serve as soft templates. In this study we have simulated the self-assembly of hexadecyltrimethylammonium chloride (C16TAC) surfactants at the Si(1 0 0)- and Si(1 1 1)-aqueous interfaces. The surfactants are found to form semicylindrical micelles on Si(1 0 0) but hemispherical micelles on Si(1 1 1). ...
