摘要： The present invention provides a method of recovering a heavy metal by which the variation in heavy metal recovery rate among samples can be suppressed. A mixture of a sample and a chelating agent capable of chelating with a heavy metal is prepared. A complex between a heavy metal being in the sample and the chelating agent is formed in the presence of a masking agent for a thiol group in the mixture. The heavy metal in the sample is recovered by recovering the complex. By this method, a heavy metal can be recovered with suppressing the variation in the recovery rate among samples. The chelating agent preferably is 1,5-diphenyl-3-thiocarbazone (dithizone). As the masking agent, N-ethylmaleimide, iodoacetamide, iodoacetic acid, or the like can be used.

摘要： 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 being in a sample is formed in a mixture prepared by mixing the chelating agent and the sample under a pH condition 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 a pH condition that is different from the pH condition 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.

摘要： 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 being 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 condition 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. By this method, a metal can be recovered without requiring the use of an organic medium.
