摘　　要：本文阐述了采用微波消化测定配方食品中微量的钼。用硝酸高压溶解，然后用石墨炉原子吸收测定。方法的检出Fg0．7ng／ml，线性范围0～100ng／ml，其回收率为95．1％～104．8％。该方法填补了配方食品中检测钼的空白，精密度高，检出限低。Determination of molybdenum in food formulation applies microwave digestion technique. It is deter- mined with nitric acid in a high--pressure microwave oven and then analyzed by graphite furnace atomic absorption spectrometry. The detection limit is 0.7ng/mL,The calibration lines are linear in the range of 0 -100ng/mL,and the recoveries of these materials range from 95.1% to 104.8%. The method is established for the first time, rapid, accurate and low on the detection limit.
