| Abstract: | Various test conditions and effect factors for determination of lead by transversely heated graphite furnace atomic absorption spectrometry were discussed in this paper and a method for the determination of trace lead in propolis by transversely heated graphite furnace atomic absorption spectrometry has been developed. The detection limit for lead are 0.94 μg/L under optimum conditions, The linear range is 0.94 -- 100μg/L. The relative standard deviation is 3.1% and the recovery is 95 % -- 106 %. This method is high sensitivity, accurate and little matrix interferences and has been applied to the determination of trace lead in propolis with satisfactory results. |
