ABSTRACT
<p><b>OBJECTIVE</b>To measure the contents of the water-soluble iron, five heavy metals and harmful elements in Magnetiturn and provide a basis for the quality control and safety evaluation of Magnetitum.</p><p><b>METHOD</b>Iron (Fe), lead (Pb), cadmium (Cd) and copper (Cu) were determined by atomic absorption spectrometry (AAS); arsenic (As) and mercury (Hg) were determined by atomic fluorescence spectrometry (AFS).</p><p><b>RESULT</b>The mean content of element iron is 764.30 mg x kg(-1). The contents of five water-soluble heavy metals and harmful elements in Magnetitum were within the safety range. The recovery of the standard addition was in the range of 93.7% - 110.6%, and the RSD was less than 5.0%.</p><p><b>CONCLUSION</b>Analyzing the water-soluble iron, heavy metals and harmful elements in Magnetitum is effective to the quality control and the safety evaluation of magnetitum.</p>
