| 摘 要： | 碳粉在高温条件下可还原硫酸钡，使其氧转入ＣＯ２及ＣＯ气体中。此ＣＯ气体在高温镍金属的催化作用下，可转化为ＣＯ２气体。两种ＣＯ２合并后，可用质谱计分析其氧同位素组成。此组成便是硫酸钡的δ（１８）Ｏ值。水体硫酸根的氧、硫同位素值在水环境研究中大有用处。例如，三山岛金矿矿井水中硫酸根的氧、硫同位素数据表明，此水是地下水及海水的混合产物。这就为矿井排水工程的设计提供出某种信息。

| Abstract: | Carbon powder can reduce BaSO4 at hypothermal temperature to produce CO,and CO.The CO can be changed to CO2 in catalytic process of hypothermal nickel metal. Oxygen isotope composition of the sum CO2 is the value of BaSO4. The oxygen and sulfur isotope compositions of SO-dissoved in water play an important role in the research of water environment. For example,the oxygen and sulfur isotope compositions of SO- dissolved in subsurface water of Sanshandao gold mine show that the mining water is a product of mixing of sea water and mine subsurface water. |
