摘  要:
采用电感耦合等离子体原子发射光谱(ICP-AES)法对稀土尾矿中的La、Ce、Sr、Ba元素进行了测定。研究了ICP-AES的操作条件并确定了适宜的实验条件,研究了酸度的影响以及谱线干扰的消除。样品平行测定的相对标准偏差小于1.6%,回收率在97.6%~103.3%之间,实现了稀土尾矿中镧、铈、锶、钡的快速、准确测定。

摘  要:
The amounts of La,Ce,Sr and Ba were quantitatively analyzed in rare earth gangue by inductively coupled plasma atomic emission spectrometry(ICP-AES).The conditions of ICP-AES operation and testing,the influence of pH and the correction of spectral interference were studied.The relative standard deviation was less than 1.6% and the recovery rate was 97.6%~103.3%.This method could be applied to rapid and accurate determination of La,Ce,Sr and Ba in rare earth gangue.
