Ion-selective electrodes directly respond to the activity of target ions without destroying the existing form of the original electrolyte, so ion-selective electrodes have been widely used in various fields. Mean activity coefficient of NaNO3 in the ternary system (NaNO3 + CsNO3 + H2O) at 298.15 K was measured by electromotive force (EMF) with the cell: Na+ ion-selective electrode (Na-ISE)|NaNO3 (mA), CsNO3 (mB)|NO3- ion-selective electrode (NO3-ISE) with total ionic strengths from 0.01 to 4.5 mol·kg-1 at different ionic strength fractions (0, 0.1, 0.2, 0.4, 0.6, and 0.8).

Thirty years of ion-selective electrode (ISE) researches at the University of Wales, Cardiff are outlined. They summarize developments of PVC membrane ISEs, first for calcium and then of other systems, including the improved calcium dioctyl-phenyl-phosphate sensor for calcium and those of ion-exchangers, polyalkoxylates, and cyclic and acyclic polyethers for various anions and cations. Electrodes based on polyalkoxylates have interesting properties toward the polyethers themselves. Some ISE failure causes are discussed.

Methods for the quantitative determination of lanthanum that have been developed are generally spectroscopic methods such as inductively coupled plasma mass spectrometry (ICP-MS), inductively coupled plasma atomic emission spectrometry (ICP-AES), and X-ray fluorescence spectrometry, which has relatively high operational costs. The feasibility of the potentiometric method using ion selective electrode (ISE) as an alternative method for lanthanum (III) determination needs to be studied because it is simple, easy to use, and has high sensitivity and selectivity.

Ion-Selective Electrode (ISE) is an emerging technology for in situ monitoring of the chemical concentrations of an aqueous environment. In this work, we reported a novel all-solid-state silicate ISE, using an Ag/Pb/PbSiO3 electrode. This electrode responded to aqueous SiO32− with a reasonable slope of −31.34 mV/decade and a good reproductivity. The linear range covered from 10−5 M to 10−1 M, for the Na2SiO3 solutions and the response time was generally less than 5 s. Its potentiometric response to pH and silicate indicated that the prepared electrode was sensitive to silicate, rather than pH.

PRED-ISE was used as an indicator electrode for the potentiometric titration of different concentrations of standard prednisolone against standardized sodium tetraphenyl borate solution and in tablets. The electrode manifests advantages of low resistance, fast response and, most importantly, good selective relativity to a variety of other cations.

Current solid potentiometric ion sensors mostly rely on polymeric-membrane-based, solid-contact, ion-selective electrodes (SC-ISEs). However, anion sensing has been a challenge with respect to cations due to the rareness of anion ionophores.

In this work, we first compared the two types of SC-ISEs of Cl− with/without the ISM.

A new solid-contact ion-selective electrode (ISE) sensitive to lead (II) ions, obtained by modifying a polymer membrane with a nanocomposite of carbon nanofibers and an ionic liquid 1-hexyl-3-methylimidazolium hexafluorophosphate, is presented. Electrodes with a different amount of nanocomposite in the membrane (0–9% w/w), in which a platinum wire or a glassy carbon electrode was used as an internal electrode, were tested. Potentiometric and electrochemical impedance spectroscopy measurements were carried out to determine the effect of the ion-sensitive membrane modification on the analytical

Ion-selective electrodes (ISE’s) have benefits for solution-phase detection and quantification of ions, such as ease of operation, low cost, and high throughput compared to, e.g., ion chromatography or mass spectrometry methods. ISE devices are traditionally operated under zero-current conditions, where analyte ions passively exchange across a selective membrane barrier, yielding a Nernstian response after equilibration of Coulombic and chemical driving forces across the membrane. However, this passive mode of operation can require long equilibration times and lead to drift, for example due to

Abstract Ion-selective electrodes (ISEs) are widely used in clinical examinations. The mechanisms of ISEs have been studied to develop a disposable ISE for "dry chemistry" analyses. The behavior of Na+ and Ag+ in an ion-selective polymer liquid membrane (ISM) containing methyl monensin (MMO), which is selective for Na+, has been clarified by x-ray microanalysis and measurement of electrical potential. The results indicate that Na+ is not transported across the membrane because of a stability of the Na(+)-MMO complex, whereas Ag+ (from the Ag/AgCl electrode) is transported with Cl- across the m
