Abstract: A process is described for electrochemically "collecting" certain organic compounds from aqueous solutions in an immobilized and concentrated manner conducive to subsequent destruction. The method is applicable for organic compounds amenable to electrochemical coupling, e.g. by condensation. The method involves the electrochemical reaction of the organic compounds to form substantially water insoluble coupling products in the form of deposits or films on the working electrode surface. This method has the advantage of greatly concentrating and immobilizing the organic compounds on the surface of the working electrode. The immobilization of the organics allows the material to be transferred to a different environment or allows the environment to be changed to facilitate destruction of the organics.
