摘要

建立了电感耦合等离子体高分辨率质谱法定量分析五羰基铁元素的方法。Fe(CO) 5的样品被转移到硝酸盐溶液中进行分析。对五羰基铁馏分的基质效应分析表明，B、Ni和Ti杂质集中在轻馏分中，Cr、Co、Cd、Mo和W杂质集中在重馏分中。五羰基中铁对广泛存在的杂质如Mg、Al、P、Cr、Ni的检出限为10 - 6 ~ 10 - 5 wt. %，对Bi、Cd、Co、Pt、Re、Tl、W、U的检出限分别为10 -8 ~ 10 -7 wt. %。

Elemental analysis of iron pentacarbonyl by inductively coupled plasma mass spectrometry

A technique for the quantitative elemental analysis of iron pentacarbonyl by high-resolution mass spectrometry with inductively coupled plasma has been developed. Samples of Fe(CO) 5 were transferred to a nitrate solution for the analysis. To account for the matrix effects analysis of iron pentacarbonyl fractions showed that the impurities of B, Ni and Ti were concentrated in the light fractions, and the impurities of Cr, Co, Cd, Mo and W in the heavy ones. The detection limits of iron in pentacarbonyl for widespread impurities such as Mg, Al, P, Cr, Ni were 10 –6 –10 –5 wt. %, and for less common impurities of Bi, Cd, Co, Pt, Re, Tl, W, U - 10 -8 ÷ 10 -7 wt. % respectively.
