本文对西藏扎布耶盐湖秋季卤水进行了25℃等温蒸发试验,并参考Na^+、K^+//CO3^2-、SO4^2-、Cl^-—H2O五元水盐体系介稳相图和Li^+、Na+//Cl^-、SO4^2-、CO3^2-、B4O27-—H2O六元(赝)体系(25℃,对NaCl及Li2CO3饱和)溶解度相图,研究了该季卤水25℃等温蒸发过程中盐类结晶路线和析出规律,为该盐湖卤水的综合开发利用提供重要的依据。
The authors conducted an experiment of 25℃- isothermal evaporation of autumn brines from the Zabuye Salt Lake, Tibet, and studied the crystallization paths and precipitation regularilies of salts in the process of isothermal evaporation of autumn brines at 25℃ by referring to the metastable diagram of the quinary water- salt system Na^+ , K^+ , CO3^2- , SO4^2- , Cl- -- H2 O and the solubility diagram of the senary (counterfeit) system Li^+ , Na^+ , Cl^- , SO3^2- , B4O7^2- --H2O (saturated in NaCl and Li2CO3 at 25℃). The experiment and study provide an important basis for the comprehensive exploitation and use of brines of this salt lake.
