硫铁矿石标准物质研制中有关问题的探讨

Some Problems in the Preparation of Pyrite Ore Standard Reference Materials

    摘要
  • 摘要: 探讨了硫铁矿石的稳定性和影响其稳定的诸因素。定量考察了硫铁矿石在存放过程中,由于空气中氧和水份的作用使低价硫逐渐被氧化为高价硫的过程。提出可用全硫(TS)作为硫铁矿石稳定性的监测项目。另外,对硫铁矿石标准物质研制中的样品采集、制备、均匀性,定值项目等问题也进行了讨论。

     

    Abstract: An investigation was made of the stability of pyrite ores and the affecting factors.It was found that the low-valent sulfur is gradually oxidized to high-valent sulfur by oxygen and water when exposed to air, which is the main reason for the unstability.
