中文摘要: 探讨了采用ChCl-urea(1︰2)低共熔溶剂为溶剂、氨三乙酸(NTA)为螯合剂浸出含锌烟尘中锌的可行性。考察了浸出温度、浸出时间、NTA浓度、液固比对锌浸出率的影响。结果表明,在浸出温度为80 ℃、浸出时间24 h、NTA浓度0.1 mol/L、液固比12.5的条件下,锌浸出率可以达到87%左右。

Abstract:The feasibility to leach zinc from zinc-bearing dust with ChCl-urea(1︰2) Deep Eutectic Solvents as solvent and nitrilotriacetic acid (NTA) as chelating agent was studied. The effects of leaching temperature, leaching time, NTA concentration, and L/S on zinc leaching rate were investigated. The results show that zinc leaching rate is about 87% under the optimum conditions including leaching temperature of 80 ℃, leaching time of 24 h, NTA concentration of 0.1 mol/L, and L/S=12.5.
