Elemental analysis of iron pentacarbonyl by inductively coupled plasma mass spectrometry

Abstract

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.
