确定水相高氯离子浓度、酸度、适当控制Ｆｅ／Ｌｉ的条件下，进而研究主要工艺条件———萃取相比、洗涤相比及反萃取相比，考察相比对锂、铁及其它杂质的萃取率、洗脱率、反萃取率、分配比和分离系数的影响，优化选择萃取、洗涤和反萃取等过程的相比。
Determine the aqueous phase of high chloride concentration, acidity, under the appropriate control of Fe / Li conditions, and then study the main process conditions --- extraction compared to washing compared to stripping compared to study compared to lithium, iron and other impurities The effects of extraction rate, elution rate, back extraction rate, partition ratio and separation factor on the optimal selection of extraction, washing and stripping processes were compared.
