中文摘要:

      本实验以玻利维亚Pastos Grandes(帕斯托斯 格兰德斯)盐湖卤水原卤为原料进行自然蒸发实验,结合Na₊^,K₊^,Mg₂₊^{// Cl}_- ^—H₂O四元体系25℃相图探究此卤水自然蒸发过程中化学组成变化、自然蒸发结晶路线和不同盐类析出顺序,根据实验结果得出此卤水各个蒸发阶段的析盐顺序及分离点,为该盐湖卤水的综合开发利用提供理论性的参考依据。

英文摘要:

      This experiment was performed on Bolivia Pastos Grandes (Pastos Grandes) salt lake brine as raw material for natural evaporation experiment, combined with Na +^{, K} +^{, Mg}2 + ^// Cl-^—H2O four element system 25℃ phase diagram to explore the chemical composition in the process of natural evaporation, natural evaporation crystallization route and different salt precipitation sequence, according to the experimental results of the brine stages of salt evaporation sequence and separation point, provide a theoretical reference for the comprehensive development and utilization of the salt lake brine.
