简介 Disclosed is a method for recycling metal-chelates by separating the metal or metal ion from the chelate by forming a metal salt or metal precipitate apart from the chelator. In various embodiments, gadolinium-chelates, which are used as MM contrast agent and which create vial hold-up material that is otherwise discarded, are acid or solvent treated to promote separation of the gadolinium from the chelate for downstream sale or further processing.
