Study of Organic Surfactant Sorption in Organophilic Clays

Abstract:

Bentonite clays, due to an immense variety of applications, are widely studied. Yet currently, organically modified bentonite clays studies have been increasing. The methods most studied involve addition of ionic or non-ionic surfactants to synthesize organophilic clays. The synthesis can be performed in two ways: by ion exchange (double replacement reaction chemistry), or by ion-dipole interaction where organic molecules are adsorbed on the surface of clay. The present work studies the sorption mechanisms of ionic and non-ionic surfactants to the surface of bentonite clays, thus making them organophilic. The results for the sorption experiments were obtained by adjusting the parameters of known mathematical models to the experimental data, the linear, and Freundlich models gave the best results for the sorption isotherms.
