Abstract:
      The copper residue can remove the chlorine ions in zinc solution effectively. The removal efficiency of chlorine is over 90% with the conditions: 10g/L of sulfuric acid, 60℃,retention time of 1 hour and 3.38g/L addition of copper residue. The concentration of fluorine ions can be lower than 100mg/L after purification. The absorption method by goethite have shown that the removal of F and Cl can be reached 60% and 35%, respectively. With extension of the time, the absorbed F and Cl ions are desorbed and released into the solution again.
