| 摘 要： | 有关双冠醚钾离子选择电极的研究已有较多文献报道。本文以双2’:3’,9’:10’-二苯并-16-冠-5)-6-基]-2,6-吡啶二甲酸酯(简称BDB16C5PDC)为中性载体,邻苯二甲酸二辛酯为增塑剂研制的钟离子选择电极、其响应斜率优于以前所报道的双冠醚钾离子选择电极。该电极的线性响应范围为1.00×10~(-5)～1.00×10~(-1)mol/l;检测下限为5.57×10~(-6)mol/l;响应斜率为67.5mv;对Li~+、Na~+、Rb~+、Cs~+、NH_4~+、Mg~(2+)、Ca~(2+)、Ba~(2+)的

| Abstract: | A new potassium ion-selective electrode which was prepared by coating a graphite rod with P VC membrane containing bis (2': 3', 9': 10'-dibenzo-16-crown-5)-6'-yl]-2, 6-pyridine-dicarboxylate as neutral carrier was deseribed. This electrode had the advantages of the simplicity of the structure, the convenience to make and the lowcost. The electrode exhibited a higher slope (up to 67.5mV) than others. |
