Regeneration of activated carbon with a solution of sorbed species in a solvent

摘要

Solvent regeneration of activated carbon on which a chemical species is sorbed is enhanced by the selective use of a regenerant solution containing a solvent for said chemical species and a predetermined concentration of the chemical species in solution. The stream of spent regenerant coming from the carbon is thereby made more concentrated in solute and easier to treat for separation of the solute and solvent.
