火焰原子吸收光谱法测定高品位、高氧化率铜矿石中氧化率的准确度研究

Study on the accuracy of flame atomic absorption spectrometry in the determination of oxidation rate of copper ore with high grade and high oxidation rate

文章主要围绕碘量法与原子吸收光谱法分别测定游离氧化铜和结合氧化铜实验方法进行对比,浸取后的试液进行稀释,采用原子吸收光谱法测定铜,干扰元素少,介质的干扰也小,准确度可靠,适合高品位、高氧化率铜矿石中氧化铜的测定。

This paper mainly focuses on the comparison between the iodimetric method and the atomic absorption spectrometric method for the determination of free copper oxide and the combined copper oxide experimental method.The test solution after leaching is diluted,and the atomic absorption spectrometric method is used for the determination of copper oxide,which is suitable for the determination of copper oxide in copper ores with high grade and high oxidation rate.
