Claim 7:
8. A method for compact and flat bismuth metal preparation by electrolysis, comprising:
1) mixing bismuth methanesulfonate and free methanesulfonic acid to obtain an electrolyte, and adding sulfonated and vulcanized alkylphenol ethoxy and naphthol ethoxy oxide to the electrolyte to obtain a mixed electrolyte consisting of the bismuth methanesulfonate, the free methanesulfonic acid, the sulfonated and vulcanized alkylphenol ethoxy and the naphthol ethoxy oxide; and
2) injecting the mixed electrolyte into an electrolytic cell, inserting an anodic plate and a cathodic plate into the electrolytic cell, and applying direct current electrolysis to obtain compact and flat bismuth metal.
