火焰偏振塞曼原子吸收光谱法直接测定钼金属炉料中铁含量

摘要

Using polarization zeeman atomic absorption spectrometry,the content of iron in molybdenum metal charge was determinated.The influence of this method on molybdenum matrix was studied.The detection limit is 0.36mg/L,the characteristic concentration is 0.18 mg/L with d the recovery of 99.2%~106.1%.%采用火焰偏振塞曼原子吸收光谱法测定钼金属炉料中铁含量。考察了该方法的钼基体影响。该方法的检出限为0．36 mg/L，特征浓度为0．18 mg/L，回收率为99．2％～106．1％。
