| 中文摘要:我国盐湖资源丰富, 尤以柴达木盆地盐湖为代表, 其卤水中富含硼、镁资源, 但由于其结构复杂, 在水溶液中存在过饱和现象, 且不稳定、易转化, 这使得其资源无法得到大规模、工业化的生产, 严重限制了我国充沛的盐湖硼资源的开发和高值化利用。本文以288.15 K作为实验温度, 对MgSO4质量分数分别为5%、10%、20%、30%溶液中章氏硼镁石的转化规律进行了实验研究, 有助于阐明盐湖镁硼酸盐形成过程机制, 对于丰富盐湖硼酸盐化学、推动盐湖卤水合理开发利用意义重大。 |

| Abstract:China possesses abundant salt lake resources, especially the Qaidam Basin salt lake, which is rich in boron and magnesium resources. However, because of their complex structure, magnesium borate aqueous solutions are affected by supersaturation solubility and solubilization phenomena, and their solid-liquid system is easily to transformed, which greatly limits the efficient development and economic utilization of liquid boron resources. In this paper, the transformation rule of hungchaoite in MgSO4 solution with mass fraction of 5%, 10%, 20% and 30% was studied at 288.15 K. The results of the study advance understanding of the borate chemistry of salt lakes and promote the rational development and utilization of salt lake brine. |
