氢化物发生-火焰原子吸收法测定金属钼中微量砷

Determination of Trace Arsenic in Molybdenum Metal by Hydride Generation Flame Atomic Absorption Spectrometry

以过氧化氢溶解金属钼样品,氢化物发生-火焰原子吸收法测定其微量砷的含量。结果表明,该法的相对标准偏差仅9.96%,加标回收率为91.8%～102.0%,砷检出限达0.28μg/L,准确度和精密度均较高。

The molybdenum metal samples were dissolved with hydrogen peroxide and then their trace arsenic contents were determined by hydride generation flame atomic absorption spectrometry.The results show that the above method is of good accuracy and precision with 91.8%～102.0% standardized recovery,9.96% RSD,0.28 μg/L arsenic detection limit.
