The atomic absorption spectrophotometric determination of beryllium in aqueous solutions and the effect of some water-miscible organic solvents were studied in a nitrous oxide-acetylene flame, using a Perkin-Elmer Model 303 atomic absorption spectrophotometer. The beryllium atomic absorptions were measured at the 234.9-nm resonance line of beryllium. The sensitivity for beryllium was 0.03 ppm for a 1% absorption. With the exception of palladium and silicon, none of the elements interfered with the determination of beryllium. Phosphoric acid caused an enhancement, while hydrochloric and nitric acids had a slight depressing effect. Furthermore, there seems to be a tendency for organic solvents with a higher ratio of the number of carbon atoms to that of oxygen atoms to cause greater enhancements in beryllium absorption, though there are a good number of exceptions. The atomic absorption method was applied to the determination of beryllium in several aluminum-, copper-, and magnesium-base alloys, with satisfactory results.
