Abstract

To optimize operating conditions for separation and recovery method with a porous type anion-exchange resin, a competitive adsorption model was developed by considering mass transfer and ion-exchange reactions of each component. The model well described the concentration profiles adsorbed in the axial direction of the column packed with the resin, which are difficult to determine experimentally, in addition to the concentration profiles in the effluent from the column. The model was also able to predict optimum operating conditions to maximize the recovery yield of the target material and is effective for the process design of the recovery method with the resin.
