Currently there are increasing studies on bentonite clays are organically modified. Since the method involves the addition of surfactants (sufactantes) ionic or nonionic most studied in the synthesis of organoclays, so that the synthesis can be performed in two ways: by ion exchange (the chemical reaction of double exchange) and ion -dipole (organic molecules are adsorbed on the surface of clay). Thus, the present work aims to study the sorption / cation exchange of ionic and nonionic surfactants on the surface of bentonite clays making them organophilic. In the process of organophilization bentonite clays have used two industrialized Brasgel PA and the Bentongel that their concentrations were varied from 3.16 to 7.16% by weight of...
