锂与其他碱金属和硷土金属的分离可采用离子交换法。采用稀无机酸水溶液作淋洗剂时,为了将锂全部洗脱,需要800毫升淋洗液,而分离的锂/钠比值仍受到限制。Багбанли的实验表明,当钠:锂大于10:1时,须先将钠除去。仰蜀薰采用0.2M HCl:甲醇=7:3的混合淋洗剂,将可分离的钠/锂比值提高到48:1。Nelson采用HCl-甲醇-水混合液作淋洗
Lithium and other alkali metal and alkaline earth metal separation can be used ion exchange method. When a dilute mineral acid aqueous solution is used as the eluent, 800 ml of eluent is required to elute all of the lithium while the lithium / sodium ratio of the separation is still limited. Experiments in Багбанли show that when sodium: lithium is greater than 10: 1, sodium must first be removed. Yang Shu-hua using 0.2M HCl: methanol = 7: 3 mixed shower, the detachable sodium / lithium ratio increased to 48: 1. Nelson uses a HCl-methanol-water mixture for rinsing
