Objective To evaluate the uncertainty for the determination of iron in grape wine by atomic absorption spectrometry. Methods According to GB/T 15038?2006 General Analysis Method for Wine and Fruit Wine, a uncertainty mathematical model for of the determination of iron content in wine was established. Results When the iron content in grape wine was 3.806 mg/L, the expanded uncertainty of iron content in grape wine was 0.376 mg/L. Conclusion The main sources of uncertainty are caused by preparing standard solution and drawing the working curve.
