Abstract
A simplified method for the atomic adsorption determination of antimony is described. Samples are dissolved in hydrobromic acid and diluted to volume with water. Solutions can be ready for analysis in about 10 minutes and are stable for at least 24 hours. The spectral line at 231 nanometers is used, and there is no effect on adsorption resulting from the presence of any concentration of hbr. Absorbance is linear with antimony concentrations up to 120 micrograms per milliliter. Sensitivity is 1.48 Micrograms per milliliter per 0.0044 Absorbance. Relative errors on National Bureau of Standards standard reference materials were 3 percent or less, and relative standard deviations on 12 determinations of each of three flue dust samples were 4 percent or less (95-percent confidence limit).
