摘要
研究了以抗坏血酸+琥珀酸为浸出体系从废三元锂电池中回收镍、锂,考察了琥珀酸加入量、浸出时间、浸出温度、抗坏血酸浓度对镍、锂浸出率的影响。结果表明:在固液质量体积比2 mg/1 mL、琥珀酸加入量4/1、抗坏血酸浓度为0.2 mol/L、浸出时间40 min、浸出温度80℃最佳浸出条件下,镍、锂浸出率分别为95.58%和97.57%。该有机酸体系浸出效果较好。
The leaching system of ascorbic acid+succinic acid was used to recover nickel and lithium from waste ternary lithium batteries.The effects of succinic acid dosage,leaching time,leaching temperature and ascorbic acid concentration on the leaching rate of nickel and lithium were investigated.The results show that under the optimal conditions of solid mass/liquid volume ratio of 2 mg/1 mL,succinic acid dosage of 4/1,ascorbic acid concentration of 0.2 mol/L,leaching time of 40 min and leaching temperature of 80℃,the leaching rates of nickel and lithium are 95.58%and 97.57%,respectively.The leaching effect of the organic acid system is good.
