| 摘 要： | 采用离子交换法,从锂离子电池正极硫酸浸出液中分离、提纯并回收其中的钴.实验研究了浸出液pH、漫出液循环次数等因素对浸出液中钴和主要杂质铜分离的影响.结果表明:使用TP207树脂,保持锂离子电池正极浸出液pH为2.5,使溶液循环通过树脂10次,可使Cu离子去除率达到97.44%,钴离子的回收率达到90.20%,处理后所得产物可用作工业原料.此方法操作简单,有实现大规模工业化应用的潜力.

| Abstract: | Ion-exchange method was used to separate,purify and reclaim the cobalt from the anode sulphoacid leachate of lithium -ion battery.Effects of leachate pH and circulation times on separation of cobalt and copper in the leachate were researched.The results showed that at the optimal conditions(anode leachate pH was 2.5 and 10 circulation times),the removal ratio of Cu-ion reached to 97.44%,and the recovery ratio of Co-ion was up to 90.20% by using ion-exchange resin TP207.The product could be used as a raw mat... |
