title: Determination of iodine by atomic-absorption spectrometry using the platinum-loop technique.
abstract: The use of a platinum-loop atomizer and an electrodeless discharge lamp has been applied to the atomic-absorption determination of mercury at the 183.0-nm resonance line. Oxygen was flushed from the light-path with argon, giving adequate readiation transmission characteristics and a sensitivity of 9 ppm of iodine for 1% absorption. The method is prone to both cationic and anionic interferences, but the use of cation-exchange and solvent-extraction procedures overcomes some of the problems.
