Summary: Reliable potentiometric ion sensing in complex samples remains a great challenge for polymeric membrane ion-selective electrodes (ISEs). Electrode fouling caused by the adsorptions of organic molecules and biological cells seriously affects the performance of ISEs. Development of polymeric membranes with fouling resistance is a fundamental strategy to address this issue and has become an important research direction.

Summary: In this study, the ion selectivity of two ion intercalating electrodes was investigated for capacitive deionization (CDI). The results showed that the ion selectivity was influenced by factors such as the hydrated radius, valence state of the ions, and intrinsic charge of the electrode materials. The electrodes exhibited higher selectivity for ions with smaller hydrated radius and divalent ions due to stronger intrinsic negative charge.

Summary: Research in recent years has focused on the development of solid-contact ISEs for calibration-free measurements in long-term, in situ analysis. This review discusses the definition of calibration-free usage and relevant literature, with a focus on different mechanisms of ion-to-electron signal transduction and different types of transduction modes.

Summary: Solid-contact ion-selective electrodes (SCISEs) are the best electrode embodiment for miniaturized, wearable and disposable sensors for ion/electrolyte measurements in body fluids. However, large scale manufacturing with reproducible calibration parameters is a challenge for SCISEs. The galvanostatic intermittent titration technique (GITT) is introduced to determine the optimal preadjustment potential.

Summary: This work characterized the potentiometric response of solid-contact ion-selective electrodes with thin-layer ion-selective membranes. The anomalous increase in potential at low concentrations of the primary potassium ion was found to be influenced by the solid-contact material, thickness of the membrane, and timescale of the measurement. It was concluded that the anomalous response is a characteristic feature of these electrodes and can be used as a diagnostic tool.

Summary: This study investigated the use of transition metal hexacyanoferrates (MHCF) as selective electrodes for capturing NH4+ in brine for nutrient recovery from wastewater. The electrochemical characteristics of five different MHCF electrodes were studied, and their desalting capacity, stability, and energy consumption were evaluated. Results showed that the NiHCF electrode exhibited the best performance in terms of specific desalination capacity, charge efficiency, and stability. This study demonstrates the promising potential of MHCF as selective electrodes for nutrient removal and recovery in wastewater.

Summary: Miniature solid-contact ion-selective electrodes using commercial mesoporous carbon black as ion-to-electron transducer showed stable electrode response, near-Nernstian slopes, and fast response in mixed electrolytes with interfering ions. These electrodes can be stored in air and used directly without conditioning, offering a low cost and convenient alternative to bulk ISEs.

Summary: The fabrication of laminated graphene paper solid-contact ion-selective electrodes (SCISE) with performance equivalent to state-of-the-art SCISEs was reported. The electrodes, prepared from commercially available graphene paper, had a low cost and were able to achieve high accuracy and selectivity in ion detection. The use of graphene paper electrodes provides a cost-effective alternative to traditional options like glassy carbon and platinum rod electrodes.

Summary: The research on ion-measuring devices has rapidly expanded in recent years due to growing interest in wearable sensors for biofluids analysis and portable devices for water and food quality monitoring. Despite the apparently simple transduction principle, the theory behind their working mechanism is far from trivial, and a correct understanding is necessary for optimal exploitation of the technology. Misleading sensor parameters due to imprecise characterization procedures in current literature highlight the importance of accurate and reproducible characterization of potentiometric ion-sensors.
