Patent number: 7494630Abstract: A new method to strip metals from organic solvents in a manner that allows for the recycle of the stripping agent. The method utilizes carbonate solutions of organic amines with complexants, in low concentrations, to strip metals from organic solvents. The method allows for the distillation and reuse of organic amines. The concentrated metal/complexant fraction from distillation is more amenable to immobilization than solutions resulting from current practice.Type: GrantFiled: June 25, 2003Date of Patent: February 24, 2009Assignee: The United States of America as represented by the United States Department of EnergyInventors: Terry A.
