采用自催化还原法回收化学镀镍废液中的镍离子。通过对溶液pH、温度、ρ(NaH2PO2.H2O)及反应时间等几个因素的控制进行单因素试验和正交试验,确定镍回收的最佳工艺条件为:pH为1011,θ为80℃,ρ(NaH2PO2.H2O)为50 g/L,t为60 min,镍粉的回收率可达96%以上。对最优条件下回收的镍粉进行电子扫描电镜检测,结果表明,制得的镍粉呈圆球状,分散均匀,粒径大约在2μm,属于超微粒镍粉,具有很好的应用价值。

In this paper,the autocatalysis reduction method was used to recycle the nickel ions in the wastewater of electroless nickel plating.The single factor and orthogonal experiments were designed under different pH value,temperature,NaH2PO2 · H2O concentration and reaction time.The optimized operation conditions were obtained with pH value of 10~11,temperature of 80 ℃,reducing agent dosage of 50 g/L,reaction time of 60 min.Under this optimal condition,the recovery rate of nickel could be up to 96%.The SEM results showed that the nickel powder obtained is in spherical and uniform with the grain size of 2 μm,and have a wide application in industry.
