Title: Method for removing impurity of bismuth electrolytic solution
Inventor: TAKANO MASATOSHI
IPC: C22B3/46
Filed: 2016-10-28
Abstract: PROBLEM TO BE SOLVED: To provide a method where, from an electrolytic solution largely containing silver as impurities, the silver is removed to obtain metal bismuth of high quality.SOLUTION: To a hydrofluosilicic acid solution containing bismuth and silver, a metal potentially baser than silver is added, and mixing and stirring are performed in a reduction atmosphere. In the reduction atmosphere, at a value with a silver oxide silver electrode as a reference electrode, it is controlled to an oxidation-reduction potential preferably of 400 to 518 mV. When the metal baser than the silver as impurities is added, by cementation reaction utilizing the oxidation-reduction of the added metal and silver ions dissolved into an electrolytic solution, the silver as impurities is reduction-precipitated into a metal so as to be removed from the electrolytic solution. Thus, metal bismuth with high purity can be obtained.SELECTED DRAWING: Figure 1
