Abstract
A radiochemical separation was developed for the determination of merc ury in biological fluids and tissues. Mercury-197 was effectively sepa rated from Br-82 and other spectral interferences employing an oxidati ve digestion using concentrated sulfuric acid and potassium permangana te with separation of the mercury tetrahedral chloride complex on Dowe x anion-exchange resin. The developed procedure gave quantitative reco veries for mercury in whale blood (99% for methylmercury and 101% for inorganic mercury). Mercury concentrations of NIST SRM 1577b and NIST SRM 2672a; both Elevated and Low level; were also determined and found to be in close agreement with reported values. A procedure to correct for the interference of Au-198 was also reported.
