Environment-friendly tin electrorefining electrolyte

The invention discloses an environment-friendly tin electrorefining electrolyte. Per liter of the electrolyte comprises 20-120 grams of H2SO4, 4-40 grams of Sn2+, 5-50 milligrams of glycoside, 1-20 grams of besylate, 0.1-2 grams of Beta-naphthol, and 0.1-5 grams of latex. In a prior tin electrorefining electrolyte, cresol sulfonic acid is generally added to suppress the oxidation of Sn2+ in the electrolyte and improve the electrolyte stability and cathode tin morphology. However, cresol sulfonic acid has a large odor, is toxic and harmful, and deteriorates the working environment of an electrolysis workshop. Therefore, the invention proposes the environment-friendly tin electrorefining electrolyte. The electrolyte has the advantages of being safe, non-toxic and efficient, and improving thedensity of the cathode tin flatness, and can be applied and popularized in the tin electrorefining industry. 本发明公开了种绿色环保型锡电解精炼电解液，所述电解液含有20~120g/L HSO、4~40g/L Sn、5~50mg/L糖苷、1~20g/L苯磺酸盐、0.1~2 g/L β-萘酚、0.1~5g/L乳胶。传统锡电解精炼电解液中般添
