Process for producing nickel hydroxide from elementary nickel. |
摘要 |
The invention provides a method of producing nickel hydroxide from elemental metal. Elemental nickel is first introduced into an aqueous ammonia or ammonia/ammonium salt solution capable of dissolving nickel. The potential, as measured by a standard calomel electrode, is allowed to reach a negative or reducing level. Oxygen is added to the aqueous solution at a rate that maintains the negative potential to facilitate the conversion of elemental nickel to nickel hydroxide. Nickel hydroxide may be readily precipitated from the aqueous solution. <IMAGE> |
