Abstract

As a result of the consumption of hazardous chemicals and their pollution on the environment, the use of different stabilization and adsorption methods and the application of clay liners for prevention of dispersion and leaching of such chemicals have become a significant task in recent years. Organophilic Bentonites, due to their large surface areas, negative charges on their particles, and high adsorption characteristics could have many applications in treatment of contaminated sites. The above mentioned characteristics of MODIFIED BENTONITEs have enabled them to attract contaminants from solutions or stabilize them in soils. This study focuses on interlayer change of Bentonitic clays due to adsorption of aromatic contaminants. The results of X- ray diffraction analysis of MODIFIED BENTONITE samples indicated a 44.2% interlayer increase after their exposure to gasoline while that of ORDINARY BENTONITE samples was insignificant (5.16%). Similar observations were noticed for other aromatics contaminant, hence denoting their Organophilic properties. It should be mentioned that the highest Interlaminar change for MODIFIED BENTONITE particles occurred in adsorption of MTBE with 48% increase (from 28.6A0 to 42.32 A0) while with the water shows 4.5% increase which is the lowest adsorption.
