In the process of nickel production and nickel electroplating, nickel-extracting resin will produce a large amount of low-concentration nickel sulfate solution, generally containing Ni2+ is 1~10 g/L, and the amount of wastewater discharge is large. If it is discharged directly without recycling, it will not only cause resources waste and pollute the environment.

Ion exchange technology is widely used due to its advantages of good effluent quality, recovery of useful substances, and suitable for treating nickel-plating wastewater with low concentration and large amount of wastewater. Jiangsu Kingshan New Material Professional Nickel Extraction Resin has the characteristics of high mechanical strength, easy analysis and regeneration, and long service life.
