摘　　要：针对西藏拉果错湖水,研究5℃恒温蒸发过程析盐规律,获得蒸发过程液相中各元素的富集行为和盐类析出规律,并参考Na+、K+//Cl-、24SO-–H2O四元水盐体系相图对结果进行分析,为以后该盐湖的合理开发利用提供基础实验数据.同时蒸发剩余卤水中Li+的质量浓度由初始0.281,g/L增加为4.938,g/L,形成了很好的提锂原料.The salt forming law of the brine from Laguocuo salt lake was experimentally investigated with an evaporating process at a constant temperature 5,℃. The concentration of the elements in the liquid phase and the salt forming law of the evaporation process were abtained. The experimental results were analyzed by referring to the quaternary system of Na＋, K＋//Cl-,24SO--H2O diagram,and have provided some basic data for the comprehensive exploitation and utilization of this salt lake. The experiment results show that the concentration of lithium ion in the residual brine increasesd to 4.938,g/L from 0.281,g/L.It could be a good raw material for extracting lithium.
