Abstract
An accurate in-situ digestion method was developed for this approach to separate the traces of Pb, Mn and Zn from their concomitant in serum samples, prior to determination by ETAAS. Pd was used as a modifier to stabilize the analyte from decomposition at 900-1000 (\degree C). Stabilization was much more effective if the mixture modifier and digested sample were first pre-pyrolyzed
