中文摘要:

      H，Li，Mg／Cl－H2O对体系的相平衡关系研究对于从锂的液体资源中有效的分离提取锂盐有重要意义。用实验的方法研究这样复杂的气－液－固多相体系是耗时费力、难度很大的工作。利用现代电解质溶液理论，开展这种体系的溶解度预测，显然有理论和实际意义。本文报导我们在这一方面的前期工作，即适用于高离子强度的HCl的Pitzer参数的获得的问题。文中给出了一些有意义的结果。

英文摘要:

      The quaternary HCl -salt system, such as H, Li,Mg/Cl- H2O is very important for re-covery of Li from Li liquid resource. Investigation of phase equiliberium in the system by Pitzer model of electrolyte obviously is useful. This paper puts emphasis on parameterization for HCl and gives some interseting results.
