Separation of organic contaminants from groundwater by complexation with the macrocyclic ligand Cucurbituril

Cucurbituril is a macrocyclic ligand which is able to remove aromatic compounds from aqueous solutions. In these complexes the hydrocarbons are located inside the hydrophobic cavity of cucurbituril. In the regeneration process ozone destroys the substances included in the cavity of cucurbituril without oxidising the macrocyclic ligand itself. Several charging/regenerating cycles are possible.
