In this paper, the migration arsenic from stainless steel food containers and table wares was determined by Graphite Furnace Atomic Absorption Spectrometry with 0.1g/100mL palladium nitrate and 1g/100mL ascorbic acid. The linear range of this method was 0-40μg/L, the correlation coefficient, R≥0.995, the detection limit, 0.001 mg/dm2, the recovery rate, 85.6%-106.6% and the precision, 3.46%-6.75% respectively. The method is simple, rapid, accurate and sensitive. It is fit for the determination of the migration arsenic from the stainless steel food containers and table wares.
