Abstract

The phenomena of adsorption is extremely important in water/wastewater treatment process. A process which uses flyash as the sorbent for removing organic compounds from aqueous solutions has been investigated. Also, the rate at which this process occurs, i.e., the kinetics of adsorption, has been studied. Single solute systems were examined and the samples were analyzed using a Flame Ionization Detector Gas Chromatograph. The potentialities of adsorption on flyash as a method of renovation of water have not been realized fully, because little knowledge is available regarding the effective application of the method for this purpose.

Flyash has been known to exhibit adsorptive and ion exchange capabilities. This is essentially due to its carbon content. Furthermore, it is an inexpensive and easily obtainable material.

The results of this investigation indicates that adsorption of organic compounds onto flyash is feasible. The time taken for adsorption is high when compared to that of activated carbon. The efficiency of the process depends upon the characteristics of flyash, the system condition and the properties of the organic compounds present in the system.
