title: The use of ozone as the primary digestion reagent for the cold vapor mercury procedure.
abstract: Ozone was tested as an alternative digestion/oxidation system to the permanganate/peroxidisulfate currently used in the cold vapor mercury method. The results indicate that the digestion of comparable size samples to the 'Standard Method' was complete in less than 2 min. A 0.5 ml (10 ppb) sample size was completely oxidized in less than 30 s. The batch system used produced a limit of detection (LOD) for mercury(II) chloride, methylmercury chloride, and phenylmercury acetate of about 0.5 ppb.
