新疆于田县优质富锂富锶天然饮用矿泉水及其开发前景

为了调查新疆于田县的水质和水资源特色，2010 年和2012 年在新疆于田县及于田县邻区采集水样，并对其元素含量进行分析测定。结果在新疆于田县新发现一个优质天然富锂富锶饮用矿泉水水源，水化学类型为Na·Mg-HCO₃·Cl，锂含量1 765.5 μg/L，锶含量1.1 mg/L，分别为国家饮用矿泉水锂（Li≥200 μg/L）和锶（Sr≥0.2 mg/L）最低界限指标的8.8 倍和5.5 倍。于田县城饮用矿泉水含水层厚度大，岩性为卵砾石，透水性好，水量较丰富。于田县优质矿泉水与国内外主要矿泉水相比，具有富锂、富锶等有益元素，且富锂矿泉水是中国稀缺的矿泉水资源，因此具有广阔的市场前景。

High Quality Natural Li-rich and Sr-rich Drinking-Water in Yutian County,Xinjiang and Its Development Prospect

To study the characteristic of water quality and water resources in Yutian, Xinjiang, China, the element content of drinking-water was measured by hydride generate atomic fluorescence spectrometry (HG-AFS), ICP-OES and ICP-MS. A high quality natural drinking water (hydrochemical type: Na·Mg-HCO₃·Cl) of Li-rich and Sr-rich was found in Yutian County, Xinjiang. The concentrations of Li and Sr in drinking water were 1765.5 μg/L and 1.1mg/L respectively, which were 8.8 times and 5.5 times that of the lowest limit of drinking natural mineral water standard (Li ≥ 200 μg/L and Sr ≥ 0.2 mg/L), respectively. The concentrations of total dissolved solid (TDS), total hardness (TH) and other trace elements were within safety range. The aquifer is the Quaternary gravel formation, with good permeability of water and relatively abundant groundwater resources. Drinking natural mineral water in Yutian was rich in Li and Sr compared to others of domestic and overseas. Mineral water with Li-rich is scarce in China. It is worth exploiting as a drinking mineral water.
