| 摘 要： | 测定了Li+,Na+,K+,Mg2+//Cl-,SO42--H2O卤水体系25℃等温蒸发过程中的密度,并分析和研究此过程的密度与蒸发水量、卤水离子组成、离子强度、析盐种类等之间的关系,并与天然含硼卤水体系等温蒸发过程的密度进行了对比。应用Pitzer体积性质模型预测了体系蒸发过程中的液相密度,并与实验测定值相比较结果一致。

| Abstract: | The densities of the brines in the process of isothermal evaporation for the system Li~+,Na~+,K~+,Mg~(2+)//Cl~-,SO_4~(2-)-H_2O at 25℃ have been measured.Further,relationships of the density with evaporated quality of water,ionic concentration,total ionic strength,crystallizing salt kind have been analyzed and discussed.The densities for this system were compared with the natural system containing borate.The Pitzer model of the volumetric property was applied to predict the volmetric properties and the densities in the process of the evaporation for the system at 25℃,with the result that the density values calculated are in a reasonable agreement with the measured values. |
