OBJECTIVE To determine the content of element of Fe in hemin oral solution.METHODS Flame atomic absorption spectrometry was used.RESULTS The calibration curve was linear in the range of 1~5μg·mL -1 for the element of Fe(r=0.9996).The average recovery of the element of Fe was 100.15% with RSD of 0.67%(n=5).CONCLUSION This method is simple and sensitive.
