Abstract
The invention discloses a method for removing copper in a nickel electrolysis anode solution for purification. The method includes the steps that reducing agents are added into the nickel electrolysis anode solution to adjust the redox potential of the nickel electrolysis anode solution; dilute sulphuric acid is used for adjusting the pH value of the solution to 1.3-4.0, and the temperature of the solution is controlled within the range of 50-70 DEG C; barium sulfide powder is added into the adjusted solution, is stirred at the temperature of 50-70 DEG C and reacts for 20-50 minutes, hot filtering is carried out, and the copper content in the solution is measured by collecting the filtrate. The method for removing the copper in the nickel electrolysis anode solution for purification has the advantages of being obvious in purification effect, easy to operate, low in operation cost, environmentally friendly, no-toxic and the like.
Description
Technical field
The present invention relates to a kind of method purifying copper removal in nickle electrolysis anode solution.
Background technology
Metallic nickel accounts for critical role in national economy, is important strategic resources and purposes metal simple-substance material widely.In practical application, nickel is mainly used in the component of special purpose, precision instrument and military equipment material with the form of alloying element, is requisite additive in military, machinery, iron and steel and aeronautical material.Nickel can form the different metal alloy compositions of purposes in proportion with other metallic substance, as nickel base heat resistant material, Nickel-based Corrosion-resistance Materials, nickel-base antiwear material and Ni-based accurate material with memory.Nickel-bass alloy material is widely used in the fields such as aviation, biology, chemical industry.Wide nickel market is proposed strict demand to the purity of nickel and quality.In the electrolytic process of nickel, the cupric ion in nickle electrolysis anode solution, once inflow negative electrode can be separated out at negative electrode prior to nickel, affects electric nickel quality, and therefore nickle electrolysis anode solution purification copper removal becomes the key ensureing electric nickel quality.The present invention is mainly for the purification copper removal of nickle electrolysis anode solution, can be used as a kind of copper-removing method produce at electrolytic nickel or use under analogue, reduce liquid copper ion content, ensure the quality product of electrolytic nickel, there is actual using value and very large market potential.
Summary of the invention
The object of the present invention is to provide the method purifying copper removal in a kind of copper removal nickle electrolysis anode solution effective, easy and simple to handle.
In order to realize above object, the technical solution adopted in the present invention is:
