    用树脂吸附从铜电解液中去除锑铋实验

    Removal of Antimony and Bismuth in Copper Electrolyte by Resin Adsorption

    • 摘要: 研究采用树脂吸附法从铜电解液中去除锑、铋杂质,考查树脂对锑、铋的吸附能力,溶液流速和温度对锑、铋吸附的影响,以及洗脱剂类型、温度和添加剂等因素对锑、铋洗脱的影响。结果表明:树脂对锑、铋的吸附能力相同;降低溶液流速和提高温度均可提升锑、铋的吸附率;动态吸附实验中,树脂对铜电解液中的Sb、Bi、Pb和Fe有吸附效果,平均吸附率分别为94.4%、97.3%、75.9%和28.3%;锑的洗脱效果主要受酸度和Cl-浓度影响,铋的洗脱效果主要受Cl-浓度影响;一定温度下,在高浓度盐酸溶液中加入少量硫脲有利于Sb(V)的洗脱。

       

      Abstract: Resin Adsorption was adopted for removal of Sb and Bi in copper electrolyte. A series of investigations were done respectively on: adsorption capacity of resin for Sb and Bi, affects of solution flow rate and temperature for the adsorption of Sb and Bi, affects of eluent types, temperature and additives for the elution efficiency of Sb and Bi. The experimental results showed that, the resin has the same adsorption capacity for Sb and Bi, the adsorption could be improved by the solution flow rate reducing and the temperature increasing. In the dynamic adsorption test, the resin has adsorption effect on Sb, Bi, Pb and Fe in copper electrolyte, and the average adsorption rates are 94.4%, 97.3%, 75.9% and 28.3%, respectively. The elution of Sb was mainly influenced by the concentrations of H+ and Cl-. The elution of Bi was mainly influenced by the concentrations of Cl-. It was beneficial for the elution of Sb (V) by adding thiourea in high concentration HCl solution at a certain temperature.
