| 摘 要： | 本实验以西藏高原腹地扎布耶盐湖冬季富Li+卤水为研究对象 ,首次通过现场实验研究该组成的卤水在系列冷冻温度下的组成演变规律。实验结果表明 ,冷冻温度对卤水中CO2 -3 浓度有较大的影响作用。卤水中的CO2 -3 浓度随温度降低而下降 ,而Li+浓度上升 ,因此 ,可采用自然冷冻法来除去卤水中CO2 -3 而使Li+有较大的富集空间。实验指出 ,冷冻时 ,只要有 - 12℃左右的冷冻空间 ,就能有效地除去卤水中CO2 -3 。

| Abstract: | The object of the experiment resarch is the winter Li-rich brine in Zabuye Salt Lake of Tibet plateau inland.Through field test the rule of composition evoltion of the brine under serial freezing temperature. The experiment results show that the freezing temperature has effective influence on the concentration of CO 2- 3 in the brine,which decreases with the descent of temperation,while the concentration of Li + increases. Therefore,natural freezing method can be used to remove CO 2- 3 in brine ,and give Li + a large room to be enriched. The experiment also shows that when freezing method is used, 12 degrees of temperature defference are enough to eliminate CO 2- 3 in the brine. |
