An adsorbate is removed from an adsorbent by contacting the adsorbent with a supercritical fluid which is a solvent for the adsorbate. The supercritical fluid containing the dissolved adsorbate is then subjected to a physical treatment which renders the supercritical fluid a nonsolvent for the adsorbate and makes it possible to remove the adsorbate from the supercritical fluid. The supercritical fluid is then subjected to another physical treatment to restore it to a state wherein it is a solvent for the adsorbate so that it may be reused. The process and apparatus are particularly suitable for adsorbent regeneration in the treating of waste water.
