摘要： 报道了饱和漆酚30-冠-10轻稀土(Ln=La～Nd)配合物的合成,通过元素分析、IR、UV、摩尔电导和DTA等方法对配合物进行了表征;并以饱和漆酚冠醚为传感活性物质,研制了镧(Ⅲ)离子选择电极,它的线性响应范围为1×10-2～1×10-6mol/L La(NO3)3,检测下限为1×10-6mol/L La(NO3)3,对镧离子的选择优于其他镧离子电极。

关键词: 饱和漆酚, 冠醚, 稀土配合物, 离子选择电极

Abstract: The complexes of rare earth (Ln = La～Nd)with saturated urushiol crown ether (DSU30C10) have been synthesized in acetonitrile solution. The complexes have been characterized by elemental analysis, IR and UV spectra, molar conductance and differential thermal analysis,The lanthanutn iOn selective electrode with saturated urushiol crown ether as a neutral carrier exhibited linear responses in 1×10-2～1×10-6mol/L La(NO3)3. The electrode showed better selectivity than other La(Ⅲ)electrodes reported in literature。

Key words: urushiol, crown ether, rare earth complex, ion selective electrode
