摘要: 本文以8个不同结构的饱和漆酚冠醚(1~8)为传感活性物质,研制了10种铊(Ⅰ)离子选择电极,综合性能最好的为1号和4号两个电极。它们的线性响应范围分别为4×10-7~5×10-1和8×10-7~1×10-1mol/L TINO3,检测下限分别为1×10-7和6.5×10-7mol/L TINO3,对钾离子的选择优于文献报道的其它冠醚铊(Ⅰ)离子电极。

关键词: 饱和漆酚, 冠醚, 铊, 离子选择电极

Abstract: Ten thallium(I) ion PVC membrane electrodes based on eight saturated urushiol crownethers were prepared.Electrodes of no.1 and 4 appeared the best ones their comprehensiveproperties.They exhibited linear responses in 4×10-7~5×10-1 and 8×10-7~1×10-1mol/L TlNO3, respectively.The electrodes showed a higher selectivity to K ion than othercrown ether Tl(I) electrodes reported in the literature.

Key words: urushiol, crown ether, thallium, ion selective electrode
