Abstract: A method for recovering a metal, capable of recovering a metal easily without requiring the use of an organic medium, is provided. A first complex between a first chelating agent and a metal present in a sample is formed in a first mixture prepared by mixing the first chelating agent and the sample. Then, the first complex is recovered from the first mixture, and a second complex between the metal derived from the first complex and a second chelating agent is formed in a second mixture prepared by mixing the first complex and an aqueous solution of the second chelating agent. The aqueous solution is under the pH conditions where the first chelating agent can be insoluble in the aqueous solution. Then, a liquid fraction containing the second complex is recovered from the second mixture. Thus, the metal can be recovered.

Abstract: A method for recovering a metal, capable of recovering a metal easily without requiring the use of an organic medium, is provided. A complex between a chelating agent and a metal present in a sample is formed in a mixture prepared by mixing the chelating agent and the sample under pH conditions where the chelating agent can be insoluble in an aqueous medium. Then, the complex is recovered from the mixture, and further, the metal is recovered by dissolving the recovered complex in an aqueous medium under pH conditions that are different from the pH conditions where the chelating agent can be insoluble in an aqueous medium. By this method, a metal can be recovered easily without requiring the use of the use of an organic medium.
