Identification and quantification of the interaction mechanisms between the cationic surfactant HDTMA-Br and montmorillonite

Using a montmorillonite and the cationic surfactant hexadecyltrimethylammonium bromide (HDTMABr), a series of organoclays were synthesized with progressively increasing surfactant loads of between 0.2 and 4.0 times the cation exchange capacity of the starting clay. Different experimental techniques...
