Innovative Process of Leaching of Nickel Supported Activated Carbon in Ammonium Sulfate

Abstract:

The leaching tests of nickel supported activated carbon under normal pressure in (NH₄)₂SO₄ were studied. The effects of experimental condition, such as initial concentration of (NH₄)₂SO₄, liquid-to-solid ratio, leaching time and leaching temperature on the leaching rate of nickel, were investigated. The results show that the leaching rate of nickel is 96.12% with initial concentration of (NH₄)₂SO₄ of 7.5%, liquid-to-solid ratio of 2, leaching time of 5h and leaching temperature of 25°C. The morphology of nickel supported activated carbon before and after leaching was characterized by XRD, which proved the effective separation of nickel and activated carbon. The leaching rate of nickel was also shown better at room temperature and atmospheric pressure. Moreover, it needn’t equipments enduring high-pressure and high temperature in the leaching process, thus reducing the costs of leaching equipments greatly. This work provides a new way to the comprehensive utilization of nickel-containing activated carbon.
