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^(-1)mol/L TINO_3,检测下限分别为1×10^(-7)和6.5×10^(-7)mol/L TINO_3,对钾离子的选择优于文献报道的其它冠醚铊(Ⅰ)离子电极。
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^(-1)mol/L TlNO_3, respectively. The electrodes showed a higher selectivity to K ion than othercrown ether Tl(I) electrodes reported in the literature.
