ABSTRACT:
Method for the regeneration of an activated carbon having adsorbates adsorbed therein characterized by removing the adsorbates by liquid dimethyl ether or a mixture of liquid dimethyl ether and water. By such method, the spent carbon can be effectively regenerated without degrading the absorption capacity and mechanical strength thereof. Further, valuable substances in the desorbed adsorbates can be effectively concentrated and recovered by a simple additional operation.
