Abstract: A determination method of palladium in norepinephrine bitartrate by adopting graphite furnace atomic adsorption has been described. The working factors of graphite furnace atomic absorption spectrometry have been optimized. The temperatures of the furnace aredryness 100 ℃, ashing 1 000 ℃, atomization 2 300 ℃, residual-erasing 2 600 ℃. The detect limit is1.55 ng/mL according the detect results of sample black (n=11), and the RSD is 3.45 % according the detect results of the medical sample (c=3.36 ng/mL, n=5). The result of test to real medical sample is satisfactory.

Key words: graphite furnace atomic absorption, norepinephrine bitartrate, palladium, trace amount
