Abstract : Successful treatment of wastewater and potable water supplies requires an accurate method of predicting bed size and service life. The design method used must effectively model multicomponent solute systems. The objective of this research is to apply the n-Finite Compartment Model to the binary system of chloroform and methyl isobutyl ketone using a microcolumn technique. An additional objective is to determine whether there exists a functional relationship between microcolumn and carbon partical diameters which affects the adsorption process. The microcolumn technique is a cost effective method of dynamically modeling the adsorption process. Reproducible breakthrough curves are obtained in a few hours using a minimal amount of carbon. The resulting breakthrough curves are numerically evaluated using the method of moments. A linear relationship, independent of column diameter, is found between the first moment and column length. Characteristics of competitive adsorption are observed when comparing the moments of pure component and binary solutions. Moments are not affected by column diameter.
