用离子交换法在“静态下”以氨基烷基磷酸基螯合性阳离子交换树脂为吸附剂,在200g/L左右的高硫酸酸度下能有效地将铜电解液中的铋和锑吸附净化掉,吸附净化率可达93%以上。吸附铋和锑的负载树脂可用盐酸作为解析剂,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。本试验为净化铜电解液中的铋、锑而提供的工艺简单而行之有效。
Ion exchange method in the “static” to amino alkyl phosphate-based chelating cation exchange resin as adsorbent, 200g / L or so high-acidity of sulfuric acid can be effectively dissolved in the copper electrolyte bismuth and antimony purification , Adsorption purification rate of up to 93%. Adsorption of bismuth and antimony loaded resin available hydrochloric acid as a resolving agent, adsorbed on the resin bismuth, antimony all resolved, the chelating resin can be returned to use. The test for the purification of copper electrolyte in the bismuth, antimony and provide the process is simple and effective.
