电感耦合等离子体质谱法测定钽铌矿中钨的含量
|
摘要
目前矿石中低含量钨的测定方法一般采用分光光度法以及ICP-AES法,随着分析技术手段的不断开发创新,ICP-MS法在痕量分析领域上优势明显。本文利用ICP-MS高分辨率、高灵敏度、低检测限、快速分析等优点,建立一种新的仪器分析检测方法,满足工业生产中对于钽铌矿中低含量杂质元素钨快速分析的要求,优于现行的行业标准制定的分析方法。经检验,ICP-MS法的分析结果准确、可靠,可在实际中应用。
Currently,spectrophotometry method and ICP-AES method are generally used to determine low content tungsten in ores.With the continuous development and innovation of analytical techniques,ICP-MS method has obvious advantages in the field of trace analysis.In this paper,ICP-MS as a new instrument analysis and detection method with the advantages of high-resolution,high sensitivity,low detection limit and rapid analysis is established to meet the requirements of rapid analysis of low content tungsten in tantalum-niobium ores in industrial production,which is superior to current analytical methods developed by industry standards.After testing,the analytical results of ICP-AES are accurate and reliable,and can be applied in practice.
