Organically modified clay mineral was prepared by exchanging hexadecyltrimethylammonium bromide (HDTMA) onto kaolinite clay
mineral. The prepared organoclay was characterized using FTIR, XRD and TGA for assigning the surface groups, layer spacing and
thermal stability. The adsorption efficiency of the produced organoclay towards hydrocarbons that likely to be present in oily wastewaters
and oil spills (gasoline and kerosene) was studied. Different process parameters as contact time, adsorbent dose and HDTMA concentration
were studied. The obtained results clarified that the adsorption capacity of the prepared organoclay was potentially enhanced than that of
unmodified clay. The batch adsorption capacity was found to be more than 5 g g-1
and 7 g g-1 with respect to kerosene and gasoline,
respectively after 24 h of contact.
Key words: organoclay, adsorption, petroleum, hydrocarbon
