AbstractTrace amounts of phosphorus have been determined in high purity iron using electrothermal vaporization inductively coupled plasma mass spectrometry (ETV-ICP-MS). The iron matrix was largely removed using solvent extraction with 4- methyl-2-pentanone. Zirconium was used as a chemical modifier to avoid interference arising from the residual iron present after solvent extraction. The use of Zr modifier did not result in P signal suppression as was observed when Ni and La were used as chemical modifiers. External calibration with aqueous standards yielded results in good agreement with reference values. The detection limit achieved using this method was 0.008 ppm P in iron.
