| Description |
Clay-surfactant hybrids were prepared from three montmorillonites of different cation exchange capacity (CEC) and iron-content using n-alkylammonium surfactants with varying alkyl chain length from C(10) to C(16). Structure of clay-surfactant hybrids were evaluated using basal spacing from XRD, organic loading from Thermogravimetric Analysis (TGA) and conformational analysis from FUR. It was found that the structure of the clay-organic hybrid depends mostly on CEC and marginally on iron-content. The systematic study of structural evolution and comparable swelling nature of clay-surfactant hybrids of the low-CEC, high iron-variety indicates its potential industrial application like high-CEC montmorillonite.
