Method for recovering a metal |
摘要 |
A method for recovering a metal by electrolysis in an electrolytic cell comprising an anode compartment and a cathode compartment partitioned by a diaphragm, characterized by supplying to the cathode compartment an aqueous solution of a water-soluble metal compound, and electrolytically reducing metal ions or metal complex ions to electroplate the metal on a cathode, wherein the diaphragm is a fluorinated anion exchange membrane made of a copolymer having repeating units of the formula: <CHEM> wherein X is F or CF3, l is an integer of from 0 to 5, m is 0 or 1, n is an integer of 1 to 5, each of p and q is a positive number and the ratio of p/q is from 2 to 16, and Y is a group involving a quaternary ammonium group. |
