Abstract:
Bentonite clay consists mostly of Montmorillonite units. Their structure is in three layers whereby the octahedral aluminium hydroxyl layer is between two tetrahedral silicon oxide layers same as the sandwich structure.
Silicon dioxide, iron oxide, and calcium oxide are the secondary components causing bentonite to have good water
adsorption and ion exchangeability properties. The interlayer of bentonite can be replaced by an ion of other metals with
lower oxidation due to the negative charge on the surface of silica or alumina. The absorption of organic compounds such as oils is a limited property of bentonite because the polar Si-OH group on the surface causes good hydrophilic properties. The capacity of bentonite for ions exchange is exploited in this study by replacing calcium ions with
cationic surfactants to improve the polarity of bentonite with three types of cationic surfactants: Cetrimonium bromide
(CTAB), cetylpyridinium chloride (CPC), and benzyl triethylammonium chloride (BTEAC). The contact angle result of bentonite and CTAB-bentonite (as quarternary amine cation) have 39.8 and 49.0 degrees, respectively. It indicated
that the metal ions between layers of bentonite are replaced by quaternary amine cation [(CH3)2NHR]+ with a large hydrocarbon chain resulting in the hydrophilic properties of bentonite being reduced
