| Abstract |
The electrolytic apparatus was so made as a barrier was immersed in the shallow pool of Bi-amalgam without reaching the cell bottom. Therefore, the Bi-amalgam was permitted to pass freely, but the supernatant solution was not to. The amalgam, agitated with two stirrers, acted as cathode on one side and as anode on the other of the cell. The electrolytes consisting of Bi(ClO₄)₃ and HClO₄ was used as the refining solution. The recommendable cathode C.D. was 5A-15A/d㎡ and the current efficiency was 100%, The amalgam refining by using 98% Bi as anode resulted in obtaining ≥5-9s. |
