Abstract:

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.

Abstract:

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.

Real-time measurements of carbonate ion concentrations in the ocean are critical to advancing marine environmental monitoring and research into deep-sea hydrothermal activity.

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.

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

This study aimed to develop simple electrochemical electrodes for the fast detection of chloride, sodium and potassium ions in human serum. A flat thin-film gold electrode was used as the detection electrode for chloride ions; a single-piece type membrane based solid-state ion-selective electrode (ISE), which was formed by covering a flat thin-film gold electrode with a mixture of 7,7,8,8-tetracyanoquinodimethane (TCNQ) and ion-selective membrane (ISM), was developed for sodium and potassium ions detection.

Abstract:

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:

Introduction Bipolar electrode (BPE) is an independent conductor immersed in the electrolyte and without directly connected to the external electronic circuit. Compared with the traditional three-electrode system, a BPE has unique advantages including a simple electrode structure, flexible sensing design, as well as the wireless driving (1). Therefore, in promoting multiplexed electrochemical detection, bipolar electrochemistery provides an effective solution for integrated design.

Human sweat, a biomarker-rich physiological fluid, is an ideal candidate for non-invasive and real-time health monitoring.

The method shows promise to be used to collect data on toxic cupric ion concentrations in saltwater environments. Abstract Free Cu is often used as an indicator for potential Cu toxicity.

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
