Abstract: A method for the determination of trace Be in aquatic products by microwave-assisted digestion with graphite furnace atomic absorption spectrometry was reported in this paper.Linear range of determination was 0-10 μg·L-1 and detection limit was 0.076 ng·g-1.RSD was 2.7% and recovery was 97.0%.The method is accurate and simple to operate.The determination results were in accordance with the results obtained by the routine digestion in an openning vessel.The method has been applied to the determination of trace Be in aquatic products.
