Determination of microgram amounts of tellurium in steels by atomic absorption spectrometry
Journal Article
·
· Anal. Chem.; (United States)
A solvent extraction procedure has been developed for the determination of tellurium in all types of steel. After dissolution, the sample is extracted with trioctylphosphine oxide-methyl isobutyl ketone. The extract is then nebulized directly into the atomic absorption burner flame. This method requires 25 minutes and can determine as low as 2 parts per million level tellurium.
