ADSORPTION WITH AUXILIARY HIGH LOADING STEP BEFORE ELUTION

摘要

An adsorption process for the separation in concentrated form of a dissolved component from a liquid stream in which the dissolved component is present in low concentration, is described. The liquid stream is passed through a bed of adsorbent until the capacity of the bed for adsorbing the dissolved component from the liquid stream is substantially reached. Then a more concentrated solution of the dissolved component is passed through the bed of adsorbent until it is more highly loaded with the dissolved component. Thereafter an eluant is passed through the bed to regenerate the adsorbent and yield an eluate containing the dissolved component in high concentration.
