Abstract
Determination of aluminium in viscera is conducted by adopting microwave digestion technique. It is determined with nitric acid in a high - pressure microwave oven and then analyzed by graphite furnace atomic absorption spectrometry. The detection limit is 0. 91ng/ml,The calibration lines are linear in the range of 0-1000 ng/ml,and the recoveries of these materials range from 95. 1% to 104. 8% . The method is simple,accurate and low on the detection limit.
