Ion-selective electrodes (ISEs) are chemical sensors with the longest history, and still probably have the largest number of applications. 1 More recently, two types of potentiometric wiretype electrodes (WTEs), such as coated wire electrodes (CWEs) 2 and solid contact electrodes (SCEs), 3,4 have exhibited rapid development. In WTEs, a total elimination of the internal filling solution provides new advantages. Simplicity of design, lower costs, mechanical flexibility, the possibility of miniaturization and microfabrication has widened the applications for WTEs in the fields of medicine and biotechnology. In SCEs of these two advanced types of WTEs, after polymerization, these polymer-coated metal electrodes were dipped into a PVC cocktail membrane solution until a bead was formed. Especially, these SCEs based on the electropolymerization method of amino derivatives onto the metal surface produced very good results, such as stabilization of the base potential, reproducibility, best selectivity, wide response ranges and fast response time. 5,6 Thus, in recent years, there have been many reports on hydrogen ion-selective SCEs 7 and hydrogen ion-selective ionophores. 8 We have studied hydrogen ion-selective ionophores and SCEs in our laboratory. 9After Simon 10 published information about tridodecylamine ionophore for hydrogen sensing, we synthesized various types of tertiary amine compound ionophores, and strived to understand the response characteristics of these ionophores. [11][12][13][14][15] Particularly, after our result concerning SCE based on the tribenzylamine (TBA) ionophore 16 was published, which had a wider response range than the electrodes with tridodecylamine (TDDA) ionophore, many types of aromatic tertiary amine compound ionophores were synthesized and studied.

Especially, we examined the responses resulting from increasing numbers of phenyl rings in ionophores, which had not been previously studied. Additionally, other common pH response characteristics of all solid-state potentiometric sensors for hydrogen ion based on poly(aniline), covered with a plastic PVC membrane and activated by these ionophores, are presented and evaluated in terms of analytical applications, such as in artificial serum an...

The electrode exhibited a slope of 44.1±1.7 mV/pH in the pH range 1.7-9.5 at 20±1 °C. Furthermore, it was observed that the electrode had good repeatability and reproducibility with a response time of 15 s and a lifetime of at least 12 months. Also, it was found to display good selectivity for H + ions in the presence of various ions. The applicability of the proposed electrode for the determination of titratable acidity in some beverages (orange juice, apple juice, fizzy drink, beer, wine and vinegar) was illustrated. It was seen that there were no significant differences between the results obtained with the proposed electrode and the traditional glass pH electrode at the 95% CL (confidence level). As a consequence, it was seen that the electrode based on ZFNCa could be successfully used as an alternative for glass electrode to determine the titratable acidity in beverages.

The Schiff base N,N'-bis(pyridin-2-ylmethylene)benzene-1,2-diamine [BPBD] has been synthesized and explored as ionophore for preparing PVC-based membrane sensors selective to the silver (Ag + ) ion. Potentiometric investigations indicate high affinity of this receptor for silver ion. The best performance was shown by the membrane of composition (w/w) of ionophore: 1 mg, PVC: 33 mg, o-NPOE: 66 mg and additive were added 50 mol % relative to the ionophore in 1 mL THF. The sensor works well over a wide concentration range 1 × 10 -3 to 1.0 × 10 -7 M by pH 6 at room temperature (slope 58.6 mV/dec.) with a response time of 10 seconds and showed good selectivity to silver ion over a number of cations. It could be used successfully for the determination of silver ion content in environmental and waste water samples.
