Graphite Furnace Atomic Absorption Spectrometry Determination of Molybdenum in Food Formulation with Microwave Digestion Technique

Determination of molybdenum in food formulation applies 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 0.7ng/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.
