用离子交换法在交换柱内，以氨基烷基磷酸基螯合性阳离子交换树脂为吸附交换剂能有效地将２３０ｇ／Ｌ左右的高硫酸酸度铜电解液中的锑和铋吸附净化掉。再以盐酸作为解析剂，将吸附到树脂上的铋、锑全部解析下来，螯合性树脂可返回使用。交换工艺流程短、设备简单、操作方便、净化效率高、费用低，不改变电解液的组分比，是比较理想的净化铜电解液的工艺流程。 Ion exchange method in the exchange column, the amino alkyl phosphate-based chelating cation exchange resin as an adsorbent exchanger can effectively 230g / L of sulfuric acid solution of copper sulfate acid and antimony bismuth adsorption purification. Hydrochloric acid is used as a resolving agent to resolve all the bismuth and antimony adsorbed on the resin, and the chelating resin can be returned to use. Exchange of short process, simple equipment, easy operation, high purification efficiency, low cost, do not change the electrolyte composition ratio, is an ideal purification of copper electrolyte process.
