采用密封溶样消解样品,以双内标校正,用碳酸盐标准物质Cui—1、Cui—2、Cui—3做标准的电感耦合等离子发射光谱法,对珍珠中稀土元素进行测定。结果表明,珍珠由于生长环境不同其稀土的含量有着明显的差异性特征。方法简便、快速、准确、可靠。 Samples were digested with sealed solution and calibrated with double internal standard. The rare earth elements in pearl were determined by inductively coupled plasma atomic emission spectrometry using the standard carbonate materials Cui-1, Cui-2 and Cui-3. The results show that the pearl has different characteristics due to its different growth environment. The method is simple, fast, accurate and reliable.
