摘要

测定硫化物矿物中的高硫含量对于地球化学、采矿和环境监测等各种应用都至关重要。虽然电感耦合等离子体光发射光谱法(ICP-OES)是硫分析的首选方法,但在处理高浓度硫时,传统的样品制备技术往往无法满足要求。本研究调查了使用 ICP-OES 准确测定硫化物矿物中硫含量的优化消解条件。我们采用了防腐蚀酸消解弹、王水-氢氟酸系统和 180 °C 的消解温度,取得了优异的结果。认证参考物质的回收率在 99.9% 到 100.5% 之间,相对标准偏差在 0.42% 到 0.84% 之间。这些结果表明该方法具有很高的准确度和精密度。本研究提出的优化消解方案为准确分析硫化物矿物中的硫提供了一种稳健可靠的方法,尤其适用于高浓度硫的分析。

Accurate determination of high sulfur content in sulfide samples: an optimized ICP-OES method
Determination of high sulfur content in sulfide minerals is crucial for various applications, including geochemistry, mining, and environmental monitoring. While inductively coupled plasma optical emission spectrometry (ICP-OES) is the preferred method for sulfur analysis, conventional sample preparation techniques often fall short when dealing with high sulfur concentrations. This study investigated optimized digestion conditions for accurate sulfur determination in sulfide minerals using ICP-OES. We employed anti-corrosion acid digestion bombs, an aqua regia–hydrofluoric acid system, and a digestion temperature of 180 °C, achieving exceptional results. Certified reference material recoveries ranged from 99.9 to 100.5%, with relative standard deviations between 0.42 and 0.84%. These results demonstrate the high accuracy and precision of the method. The optimized digestion protocol presented in this study provides a robust and reliable approach for accurate sulfur analysis in sulfide minerals, particularly for high concentrations.
