The determination of chromium in low-alloy irons and steels by atomic absorption spectrophotometry

Determination of chromium in steel by flame atomic-absorption spectrometry using a flow injection standard additions method

“…There is also a minimum volume that can be injected owing to the mode of construction of the injection valve. There are thus a number of practical restrictions on an upper value of D and so it appears sensible to select D with due regard to sensitivity, peak width and precision and then to calculate the concentration of interferent required from equation (1). This may mean that interferent has to be added to samples, if the concentration is not high enough, as was done in three of the analyses reported here.…”

Inorganic Microchemistry

“…The scope of this method can be deduced by noting its application in the determination of molybdenum and strontium (50), lead in urine (178), chromium in iron and steel (92), magnesium in iron ( 14), and iron in tungsten carbide (13), and in the estimation of trace metals in the ocean (64). Not all metals can be determined by atomic absorption spectrometry, and it is generally assumed that those metals that form refractory oxides do not lend themselves to study.…”

Ferrous Metallurgy

“…Effects of heat treatment of the specimen on determination of carbon with the vacuum spectrometer were evaluated (102,145). CHROMIUM Atomic absorption was recommended for determination of chromium in low alloy steels (108). For trace amounts (0.002 to 0.030%) the diphenylcarbazide color reaction was studied (187).…”
