| 摘 要： | 研究了在硫酸体系中回收废旧镍氢电池正极材料中的金属镍和钴. 用正交实验方法考察了浸出温度、浸出时间、硫酸初始浓度以及氧化剂用量对镍、钴浸出率的影响. 实验结果表明,各因素对镍和钴浸出率的影响程度排序均为:氧化剂用量>浸出时间>温度>硫酸初始浓度. 在实验得出的最佳浸出条件下,Co的浸出率为99.7%,Ni的浸出率为99.1%.

| Abstract: | Recovery of nickel and cobalt from anode material of waste Ni-MH battery with sulfuric acid was studied. The effect of leaching temperature, leaching time, initial concentration of sulfuric acid and quantity of oxygenant on leaching rate of nickel and cobalt was investigated with orthogonal experiments. The results showed that the degree of effect was quantity of oxygenant, leaching time, leaching temperature and initial concentration of sulfuric acid in negative sequence. Under the favorite leaching condition, recovery rate of nickel and cobalt could be reached 99.1% and 99.7%, respectively. |
