| 摘要: |
| 本文以西藏龙木错与结则茶卡为对象, 研究了两盐湖卤水在不同兑卤比情况下, 混合卤各组分的变化, 并对兑卤后的混合卤水进行了15°C蒸发过程的研究。实验分别对两种原料卤水和兑卤后卤水蒸发所得的9个卤水样品进行了常量化学组分分析, 研究了兑卤后卤水蒸发过程中盐类的富集行为和析出规律。混合卤蒸发析盐规律结果基本符合Na+、K+、Mg2+//Cl–、 24 SO?-H2O(15°C)五元水盐体系相图。 |

| Abstract: |
| This experiment research was conducted for understanding precipitation and evaporation behavior of brines collected and mixed in Longmu salt lake and Jieze salt lake in Tibet. Variations in chemical constituent concentration of the mixed brines in different mixing ratio were determined. In addition, in evaporation at 15℃, nine brine samples were analyzed in chemical composition. The result show that the concentration and precipitation of salts followed largely the law of crystallization in phase diagram of quinary water-salt system, i.e., Na
+, K+, Mg2+//Cl–, 24 SO?—H2 O(15℃). |
