Abstract
The selectivity of an adsorbent for the preferential adsorbed component of a multi-component aqueous solution is improved by means of passing an aqueous solution of the adsorbed solids eluted from the most spent stage of a multi-stage countercurrent adsorption process through a freshly regenerated bed of the same absorbent. By means of this process the preferentially adsorbed component is concentrated in the fresh bed. This invention is useful in decaffeinating aqueous coffee extracts.
