以电解法处理含镍浓缩液并回收镍,考察了电流强度、镍离子浓度、温度、pH和缓冲溶液对镍回收效果的影响。结果显示,以钌铱涂层钛板为阳极,在极距为20 mm、电流15 A、温度50 ℃、镍离子质量浓度为20 g/L并通气搅拌的条件下,镍回收率最高达到85.1%,相应的电流效率为51.8%。正交试验结果表明,镍回收率影响因素的大小顺序是电流>镍离子浓度>pH>温度。

The concentrated nickel-containing solution has been treated by electrolytic method, and the nickel re- covered. The influences of current intensity, concentration of nickel ions, temperature, initial pH and buffer solu- tion on the recovery of nickel are investigated. The results show that under the following conditions ： using Ru-Ir coated titanium plate as anode, plate distance 20 mm, electric current 15 A, temperature 50 ℃, the initial mass concentration of nickel ions 20 g/L, and by aeration and agitation, the nickel recovery rate can be...
