摘　　要：本文考察了有机溶剂 (乙酸丁酯 )及有机试剂 ( PMBP)引入 ICP- AES对稀土元素镧和钇光谱信号的影响。实验结果表明 ,有机溶剂的引入明显增大了待测物的传质效率 ,从而导致分析灵敏度的改善。与水相相比 ,有机相的引入对 ICP激发温度未产生明显影响 ,但使线对强度比 ( L og I+/I)增强 。The effect of organic solvent on spectral signals of lanthanum and yttrium in ICP AES was studied. Organic solvent can increase the transport efficiency of aerosol, and lead to the improvement of analytical sensitivity. However, the ICP temperature was not changed obviously when introducing the organic solvent.
