制备醋酸镧的清洁生产循环工艺研究

Clean Production of Lanthanum Acetate

在醋酸镧制备过程中,回收醋酸及母液中的稀土,考察回收醋酸的循环使用情况,确定减少消耗和排污、实现清洁生产的可能性。

In the production of lanthanum acetate, the acetate and rare earth in the residue solution need to be recovered and recycled. This paper researched recycling and utilization of the recovered acetate. By this research, we can determine the possibility of clean production by reducing consumpion and waster drahage.
