Abstract
Multicomponent cycling zone adsorption is studied both theoretically and experimentally using a low pressure liquid chromatography apparatus. A discrete staged equilibrium model is used to predict separations in the traveling wave mode of operation with pH as the cyclic variable. Experimental results with a glucose-fructose-water system were in qualitative agreement with theoretical predictions. Partial fractionation of glucose from fructose was achieved and a technique for obtaining pure glucose was developed. The theory is extended to predict what criteria are needed to obtain good separations by this technique. In addition a new approach for the separation of two solutes by cycling zone adsorption is presented.
