| 摘 要： | 采用动态溶出法研究了废旧镍氢电池中金属镍的湿法回收工艺。分别考察了硫酸浓度、液固比、溶解时间、温度等因素对废旧镍氢电池负极材料中镍的回收率的影响。实验结果表明,当硫酸浓度为3 mol/L,液固比为7∶1,溶解时间为5 h,溶解温度为70℃时,镍的回收率达到最高。最佳条件下,镍的回收率为98%。

| Abstract: | Recovery of nickel from anode material of waste Ni-MH battery with sulfuric acid was studied in the paper. The concentration of sulfuric acid. liquid-solid ratio, reaction time and reaction temperature were optimized. The experimental results showed the optimized sulfuric acid leaching conditions were concentration of sulfuric acid of 3 mol/L, liquid-solid ratio of 7 ： 1, reaction time of 5 h and reaction temperature of 70℃. The recovery rate of nickel was 98 %. |
