Abstract: A process is provided for the waste treatment of metal plating solutions. One embodiment of the process comprises removal of the metal values contained in solution and inactivation or destruction of the complexing agent's ability to complex heavy metals. A second embodiment comprises inactivation or destruction of the complexing agent as a first step, formation of a sludge if not formed by inactivation of the complexing agent and sludge removal. Either embodiment permits direct discharge of spent plating solutions into the environment without violation of federal or municipal regulation.
