中文摘要:

      采用高氯酸-硝酸-氢氟酸-王水处理样品，电感耦合等离子体原子发射光谱法测定硫化物矿石中的硫，筛选了样品溶液静置时间和分析谱线，测定的相对标准偏差小于1.50%，经国家一级标准物质分析验证，结果与推荐值吻合.

英文摘要:

      The quantitative analysis of S in sulfide ore，pre-treated by mixed acids ,was performed using inductively coupled plasma-atomic emission spectrometry(ICP-AES). The analytical spectral line was screened and the standing time was optimized. The RSD was lower than 1.50% which matched with the national standard value well.
