Nickel extraction resin

Nickel is one of the important strategic reserve metals, widely used in aviation, chemical and electronic fields. In the process of nickel production and nickel electroplating, a large amount of low-concentration nickel sulfate solution will be produced, which generally contains 1~10 g/L of Ni2+, and the discharge of wastewater is large. If not recycled and discharged directly, it will not only cause waste of resources, but also pollute the environment.
