在中性载体钙电极和缬氨霉素钾电极的高聚物基体或液膜内引入带酯溶性阴离子的盐如四苯硼钾和四对氯苯硼钾,能改善电极膜的性能,增强抗阴离子干扰的能力,或者能降低膜内阻,便于电极微型化。我们曾利用二叔丁基二苯并-30-王冠-10为活性材料制成了具有实用价值的钾离子选择电极。本文介绍在此电极膜内加入适量的四苯硼钾,保持选择性类似的基础上显著地减小了膜内阻,提高了电极的稳定性,用这种膜制成了微型钾离子电极。
The introduction of salts with ester-soluble anions, such as potassium tetraphenylborate and tetrakis (p-chlorophenyl) boron, into the polymer matrix or liquid film of the neutral carrier calcium electrode and the valinomycin potassium electrode improves the performance of the electrode film and enhances Anti-anion interference ability, or can reduce the membrane resistance, to facilitate the electrode miniaturization. We have made use of di-tert-butyldibenzo-30-crown-10 as the active material made of potassium ion-selective electrode with practical value. This paper describes the electrode membrane into the right amount of tetraphenyl boron, to maintain selectivity on the basis of significantly reduced the membrane resistance and improve the stability of the electrode, with this film made of miniature potassium ion electrode.
