摘　　要：采用微波消化测定动物组织中微量的铝。先用硝酸高压溶解,然后用石墨炉原子吸收测定。方法的检出限0．91 ng／ml,线性范围0-1000 ng／ml,其回收率为95．1％-104．7％．该方法简化了对动物组织中铝测定的消化,精密度高,检出限低。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.
