摘要
以镍基耐高温合金切削废料为可溶性阳极,采用隔膜电解法在氯化物体系中进行了镍产品回收的研究,考察了镍离子浓度、电流密度、电解液温度、极距等参数对槽电压(可用电压表测量)、阴极能耗及阴极电流效率的影响,并通过正交实验确定以阴极电流效率为目标的最佳电解条件为:镍离子浓度60 g.L-1,电流密度250 A.m-2,电解液温度65℃,极距25 cm,在此条件下阴极电流效率超过95%.
A process of recovering nickel was provided with hi nickel base superalloy scrap as solvent anode using membrane electro gh temperature resistant lysis methods in chloride electrolytes. The effects of parameters such as nickel ion concentration, current density, tem- perature and field pitch on cell voltage, catholic energy consumed and catholic current efficien- cy were studied. According to orthogonal test results of the goals of catholic current efficiency, optimization condition is confirmed. Nickel ion concentration is 60 g L-1, current density is 250 A m-2, temperature is 65 C, field pitch is 25 cm. Under the condition, catholic current efficiency reaehs above 95%.
