[Method] Under certain experimental conditions, the contents of trace metal ions in the Weihe River sediment were mainly analyzed by atomic absorption spectrometry, including the contents of Zn, Cu, Mg and Mn. [Result] The Mn content in the bottom mud was 469.5 μg/g, which was the highest, followed by the Zn content of 111.0 μg/g and the Mg content of 99.0 μg/g, and the Cu content was the lowest, of 8.30μg/g. [Conclusion] This method is simple and rapid with higher accuracy.展开更多
