| 本文通过揭示宵蔵盐湖卤水在浓缩过程中成盐元素的行为以及卤水水化学炎型与PH值等的变化，得出结论如下：1.卤水中主要离子的演化方向是按Ca2+→Na+→K+→Mg2+→Ca2+（阳离子）和CO32-→HCO3-→SO42-→Cl-（阴离子）顺序进行。2.除了析出固体外，微量元素一般在最后的浓缩卤水和析盐后的残余卤水中髙度富集。已査明盐湖卤水中有63种元素，其中钾、镁、硼、锂、铷、铯、铀、钍、稀土、氘已构成可以综合利用的宝贵资源。 |

| Abstract: |
| The salifiable elemental behavior on concentration as well as the variation of brine chemical types and pH value have been revealed. Some conclusions were drawn:1.The main ionic evolutional direction of brine is incremental in the order:Ca2+→Na+→K+→Mg2+→Ca2+(cation) as well as CO32-→HCO3-→SO42-→Cl-(anion). 2.In addition to the Separation of solid salt, the trace elements have a high degree of centralization in the final concentrative brine and the remnant brine after salt separation. More than 63 elements have been investigated in brine, such as K, Mg, B, Li, Rb, Cs, Sr, U, Th, Tr, D(2H), etc. Which have constituted a precious resources with comprehensive use. |
