Description

Clay plays an important role in the transport and ultimate fate of organic compounds released into the environment. The importance of adsorption processes occurring on the hydrated surfaces of clays in determining the fate of the organic pollutant compounds in the environment has motivated numerous studies to elucidate the sorption mechanisms and the nature of the surface adsorption sites. With the use of Attenuated Total Reflection-Fourier Transform Infrared spectroscopy (ATR-FTIR), the adsorption of Aniline on Ca-Montmorillonite and Na-Montmorillonite is studied. This is the preliminary step in a more extensive study of the adsorptive behavior of other organic compounds such as benzoic acid, salicylic acid, pyridine, phenol, and chlorobenzene on clays with different properties, namely: attapulgite, hectorite, and kaolin. The outcome of this experiment should bring light to the relationship that exists between organic functional groups, clay structure, or composition.
