摘要 以新型杯芳烃衍生物 ( 5,1 1 ,1 7,2 3 ,2 9,3 5-六 [( 4-苯甲酸 )偶氮基 ]-3 7,3 8,3 9,40 ,41 ,42 -六羟基杯 [6 ]芳烃 )为探针构成 PVC膜离子选择性电极 ,发现该探针对银离子有选择性 ,该电极在 1 .0× 1 0 - 5~ 2 .0× 1 0 - 2 mol·L- 1范围内有典型的 Nernst响应。对常见碱金属、碱土金属和过渡金属离子有很好的选择性 ,而 Hg2 + 、Cr3 + 、Cs+、Na+、Fe2 +有一定程度的干扰 ;此电极稳定且重复性好 ,作为指示电极已成功地应用于 Na Cl滴定 Ag NO3 Silver ion-selective electrode is prepared with PVC membranes based on calix arene derivative containing p-carboxyphenyl azo group as ionophore. Several ISEs are conditioned and tested for the selection of common metal ions. The ISEs give typical Nernstian response with a slope of 59 4 mV per decade in the concentration range of 1.0×10 -5~2.0×10 -2 mol·L -1. The ISEs exhibit stable detection reproducibility and high selectivity towards alkali, alkaline earth and transition metal ions except Hg 2+, Cr 3+, Cs +, Na + and Fe 2+. It has been applied successfully as indicator electrode in the titration of AgNO 3 with NaCl.
