| 摘 要： | 介绍了根据自己研究测定的Ｌｉ，Ｋ／Ｃｌ，ＳＯ４－Ｈ２Ｏ体系２５℃的渗透系数等热力学性质获得的Ｐｉｔｚｅｒ混合参数，并用自由能最小化方法计算了２５℃ Ｌｉ，Ｋ／Ｃｌ．ＳＯ４－Ｈ２Ｏ体系的相图。结合测定得到的该体系５０℃、７５℃的相图和复盐ＬｉＫＳＯ４转变温度的研究，整个体系相平衡和热力学的研究结果可用于盐湖卤水中锂盐的分离提取。

| Abstract: | Pitzer mixing parameters for Li,K/Cl,SO4-H2O system at 25℃ are presented in this pa- per and the prediction of solubilities in the system based on Pitzer ion interaction model is given. The obtained results and our determined phase diagrama at 50℃ and 75℃ are very useful to recov- ery and extraction of lithium salts from brines of salt lakes on Qinghai-Tibet Plateau. |
