[Determination of lead in whole blood by graphite furnace atomic absorption spectrometry with matrix modifier and L'vov platform].

Abstract

Lead in whole blood has been determined by graphite furnace atomic absorption spectrometry with matrix modifier and L'vov platform. It's found that addition of the mixture solution of 0.6% NH4H2PO4 and 0.4% NH4NO3 as matrix modifier, the ash temperature will increase up to 900 degrees C. 750 degrees C is practically used for ash temperature. D2 lamp is used… (More)
