摘要
电解溶解是一种有效的分离金属的方法,在电解槽中,对金属粉末的溶解研究,阳极溶解实验结果表明,添加硫酸铜、减小电流密度、升高温度和提高搅拌速率有利于降低槽压;增大电流密度和升高温度有利于样品的溶解。优化工艺条件为:电流密度为200 A/m2,搅拌转速20 rpm,温度为55℃,Cu2+浓度0.3 mol/L,H2SO4浓度1 mol/L。主要溶解金属有六种。
Electrolytic dissolution is an effective method for separating a metal, In an electrolytic cell, the metal powder was dissolved study, experimental results show that the anodic dissolution, Adding copper sulfate, reducing the current density, elevated temperature and stirring rate increase will help reduce the pressure tank; increase the current density increases with increasing temperature and dissolved samples. Optimization of process conditions： current density of 200 A/m2, stirring speed 20 rpm, temperature of 55 ℃, Cu2 ＋ concentration of 0.3 mol/L, H2SO4 concentration of 1 mol/L. There are six main dissolved metals.
