本文介绍一种以铟作内标,采用光谱粉末法,测定石墨中钼的分析方法。其测定灵敏度为5×10~(-4)％。出口石墨时,需要了解石墨中钼的含量。由于钼的含量低,石墨又不易分离,因而无法用化学方法分析。采用光谱粉末法测定石墨中钼,能得到比较满意的效果。分析结果与回收结果基本相符,其测定灵敏度为5×10~(-4)％。 This article describes a method for the determination of molybdenum in graphite using indium as an internal standard and spectral powder method. Its sensitivity is 5 × 10 ~ (-4)%. Export graphite, you need to understand the graphite content of molybdenum. Due to the low content of molybdenum, graphite is not easy to separate and can not be analyzed by chemical methods. Spectral powder method for the determination of molybdenum in graphite, can get more satisfactory results. The analytical results are in good agreement with the recovery results, and the sensitivity is 5 × 10 ~ (-4)%.
