    • PROBLEM TO BE SOLVED: To provide a method for recovering metal capable of easily recovering metal without using an organic medium.SOLUTION: A first complex between a first chelating agent and a metal in a specimen is formed in a mixed liquid prepared by mixing the chelating agent and the specimen under a pH condition where the first chelating agent can be insoluble in an aqueous medium. A second complex between a metal derived from the first complex and a second chelating agent is formed by recovering the first complex from the mixed liquid and by preparing a mixed liquid of a second chelating agent aqueous solution and the first complex. The aqueous solution is under a pH condition where the first chelating agent can be insoluble. Then, by recovering a liquid fraction containing the second complex from the mixed liquid, the metal is recovered. By this method, metal can be recovered without using an organic medium.
    • 要解决的问题:提供一种回收能够容易地回收金属而不使用有机介质的金属的方法。 解决方案:在第一螯合剂可溶于水性介质的pH条件下,通过将螯合剂和样品混合而制备的混合液中形成第一螯合剂和样品中的金属之间的第一配合物 。 通过从混合液中回收第一配合物并制备第二螯合剂水溶液和第一配合物的混合液,形成来自第一配合物的金属与第二螯合剂之间的第二配合物。 水溶液处于第一螯合剂不溶解的pH条件下。 然后,从混合液中回收含有第二络合物的液体馏分,回收金属。 通过这种方法,可以在不使用有机介质的情况下回收金属。 版权所有(C)2013,JPO&INPIT
