Main Article Content

Abstract

The change of modified bentonite clay surface by cetyltrimethylammonium bromide is studied by X-ray diffraction through basic d-spacing changes. The d-spacing first increases with an increase in the amount of added surfactants, and two kinds of novel arrangement of alkyl chains in interlayer of bentonite are proposed. Weight loss of modified bentonite takes place in four phases: (i) the first loss is attributed to water loss on surface and dehydration of hydrated metal cations; (ii) the second loss is due to surfactant decomposition; (iii) the third one is caused by the loss of OH functional group on bentonite layers, and (iv) the fourth is the oxidation of residual compounds, yielding CO2.
