| 摘要: |
| 溴是完备工业体系的关键必备元素。盐湖卤水是溴的重要来源。青藏高原盐湖众多，富含钾、锂、硼等资源元素，开发潜力巨大。然而，目前针对青藏高原盐湖溴含量、分布特征及其物源的研究仍然薄弱。本次研究采集了26个青藏高原盐湖表卤水样品并分析其溴含量，进一步总结其他64个已报道盐湖数据，系统分析了青藏高原盐湖溴含量分布特征，并进一步探讨了溴的可能物源。结果表明：青藏高原盐湖表卤水Br分布在0.5~246.8 mg/L之间，平均为41.1 mg/L，高溴盐湖集中分布在高原南部，呈现自南向北降低的趋势，同时，碳酸盐型盐湖平均溴含量较高，而氯化物型盐湖平均溴含量偏低；蒸发浓缩不是盐湖卤水溴富集的主控因素，盐湖中溴有多种来源，高原南部富溴盐湖溴的来源可能主要与热泉补给有关，而柴达木盆地盐湖高溴来源主要与深部地层水补给有关。

| Abstract: |
| Bromine is a key essential element in a complete industrial system. Salt lake is an important source of bromine. There are numerous salt lakes in the Qinghai Tibet Plateau, rich in resource elements such as potassium, lithium, and boron, with enormous development potential. However, research on the bromine content, distribution characteristics, and sources of salt lakes in the Qinghai Tibet Plateau is still weak. This study collected 26 surface brine samples from salt lakes on the Qinghai Tibet Plateau and analyzed their bromine content. It further summarized data from 64 other reported salt lakes, systematically analyzed the distribution characteristics of bromine content in salt lakes on the Qinghai Tibet Plateau, and further explored potential sources of bromine. The results show that the distribution of Br in the surface brine of salt lakes on the Qinghai Tibet Plateau ranges from 0.5 to 246.8 mg/L, with an average of 41.1 mg/L. High bromine salt lakes are concentrated in the southern part of the plateau, showing a decreasing trend from south to north. At the same time, the average bromine content of carbonate type salt lakes is higher, while the average bromine content of chloride type salt lakes is lower; Evaporation concentration is not the main controlling factor for the enrichment of bromine in salt lake . There are multiple sources of bromine in salt lakes, and the sources of bromine in bromine rich salt lakes in the southern plateau may be mainly related to the supply of hot springs, while the high bromine sources in salt lakes in the Qaidam Basin are mainly related to the supply of deep formation water. |
