摘 要:通过考察树脂对溶液中镁锂吸附的情况,从5种树脂中筛选出吸附容量和镁锂分离效果优良的树脂。考察了时间、pH、温度、其他盐杂质离子和镁锂比等因素对树脂吸附性能的影响。实验结果表明:ZL-5树脂对Li+、Mg2+的分离效果较好;且ZL-5树脂吸附Mg2+符合Freundlich经验式。

Abstract:The absorption of Mg2+ and Li+ in solution by resin was investigated to select the resin with high adsorption capacity and good separation effect on Mg2+ and Li+ from five resins. And the factors including time, pH, temperature, other impurity ions and the Mg/Li ratio on the adsorption properties of the resin were discussed in this paper. The test results showed that ZL-5 resin had the best separation ability on Li+ and Mg2+ among the five tested resins, and the absorption of Mg2+ by ZL-5 resin was in accordance with the Freundlich formula.
Key words:esin; adsorption; separation of magnesium and lithium
