Comparison of Wet and Dry Digestions in the Analysis of Fe in Spinach by Atomic Absorption Spectrophotometry

The method of digestion as a part sample preparation is very important to determine the accuracy analysis result. In this study, methods wet and dry digestions were applied Fe content in several kinds spinach obtained from traditional market Denpasar Bali. This research aimed compare result by AAS using both methods. was divided into steps starting sampling, determination samples species, preparation, aqua regia furnace, AAS. showed that concentrations root spinach, red cut tricolor through varied between 68.08–105.45 mg/kg, while 27.52–42.03 which over accepted value.
