IntroductionFor more than 60 years, pH-glass electrodes have been widely used, and pH measurements in various samples are still made using these electrodes. They are very popular due to their high selectivity and dynamic pH range. However, in spite of the distinctive potential characteristic of pH-glass electrodes and their use in routine pH measurements for so many years, they have certain limitations, such as high resistance, brittleness, instability in hydrofluoric acid and fluoride-containing media. They also create problems in the construction of microelectrodes for biological applications and in vivo measurements. That is why studies related to the construction of nonglass pH electrodes have been gaining momentum. The construction of PVC pH electrodes based on neutral carriers will solve most of these problems. The facts that PVC electrodes have low electrical resistance and that they are easy to construct have increased interest in the implementation of these electrodes in place of glass membranes. These electrodes are of great practical importance, since they are solid and unbreakable. For example, there have been numerous studies about the use of pH-sensitive liquid membrane electrodes in clinical studies. 1 Le Blanc et al. prepared a liquid-membrane electrode with p-octadecyloxy-m-chlorophenylhydrazonemesoxalonitrile (OCPH) as a proton carrier. 2 Simon et al. developed different PVC membrane pH electrodes based upon tri-n-dodecylamine, which gave good response characteristics. [3][4][5][6][7][8] Wu and Yu prepared a pH-sensitive electrode using methyldioctadecylamine (MDODA) as a neutral carrier.9 Later, some authors continued similar research, and other compounds have been investigated as ionophores for hydrogen ions, many of which can be used for a very wide range of pH values. [10][11][12][13][14][15][16][17][18][19][20][21][22][23] Calixarenes are metacylclophanes comprising phenolic and methylene units. They are very popular as attractive and excellent ionophores because they provide a platform for the attachment of convergent binding groups to create host molecules, mainly for the attraction of simple cations, anions and small molecules. [24][25][26][27][28][29][30][31] McKervey et al. first recognized that calixarenes with cations-complexing groups attached to the lower rim may possess the molecular requirements for the type of ionophore used in ion-selective electrodes (ISEs). 32,33 For example, the tetraesters of calix[4]arenes have been proved to be excellent ionophores for sodium in liquid membrane and PVC membrane electrodes. These types of electrodes based on such compounds were shown to be capable of measuring sodium in blood. 34,35 Some calixarenetetraesters are now commonly used in commercial blood electrolyte analyzers for sodium determination. The purpose of this study was to develop a hydrogen ionselective electrode using a macrocyclic compound of calix[4]arene as a neutral carrier and to determine its lifetime, response time, optimum working range and other response characteristics....

Natural monocrystalline pyrite and chalcopyrite were examined as new indicator electrodes for the potentiometric titration of weak acids in tert-butanol and iso-propanol. The electrodes investigated demonstrated a linear dynamic response for p-toluenesulfonic acid concentrations in the range from 0.1 to 0.001 M, with a Nernstian slope of 48 mV per decade for pyrite in tert-butanol. Sodium methylate, potassium hydroxide and tetrabutylammonium hydroxide (TBAH) proved to be suitable titrating agents. The response time was less than 12 s and the lifetime of the electrodes was higher than 1 year. The advantages of the electrodes are long-term stability, rapid response, reproducibility, easy preparation and low cost.© Versita Warsaw and Springer-Verlag Berlin Heidelberg.

“…The conducting polymer is less soluble in O and incorporated with ions, accompanied by its redox reaction, and works as an ion exchanger in O. 26 Conducting polymer-coated electrodes had been proposed as ion-electron transducers by researchers in the ISE field, and those have been applied to all-solid ISE, [15][16][17][18][19][20] in which the conducting polymer was employed instead of an inner solution in the liquid membrane type ion-selective electrode. Many reviews have been written on all-solid ISE.…”

“…4 The technical breakthrough for preparing the thin O layer is to employ a conducting polymer-coated electrode with functions of both a reference-and a counter electrode in O (reference/ counter electrode). 13,14 The conducting polymer-coated electrodes have been applied to all-solid ion-selective electrodes (all-solid ISE) with a thin organic membrane, [15][16][17][18][19][20] or to working electrodes for the stripping analysis of ionic species based on ion transfer at the W|O interface. [21][22][23][24][25] We found that the poly(3,4-ethylenedioxytiophene)-coated electrode (PEDOT-E), one of the conducting polymer-coated electrode, was useful for this purpose.…”
