Potentiometric Ion-Selective Electrodes and Ionophore-Based Sensors
This research community develops chemical sensors that measure the concentration of specific ions in water, biological fluids, and industrial samples, primarily using potentiometric electrodes and ionophore-based membranes.
The work centers on the synthesis of ionophores—molecules that selectively bind specific ions—to create selective electrodes. Recurring methods include the use of Schiff base ligands, polyvinyl chloride (PVC) membranes, and crown ethers to detect ions such as chloride, silver, zinc, and potassium. Applications range from environmental monitoring of wastewater and soil nutrients to the analysis of biological samples and industrial effluents. The research frequently involves the design of novel ligands to improve selectivity and sensitivity for specific metal ions or anions in complex matrices.
The community’s output is most heavily concentrated in research tracked for Chlorine, where it represents 0.3% of all Chlorine-related papers, and for Sodium, where it accounts for 0.1%. It also contributes significantly to research on Potassium and Silver, each with a 0.1% share.
There are 2,958 papers in this community, with the highest publication volume in Analytica Chimica Acta, Analytical Chemistry, and Talanta.
Recent work continues to focus on the development of novel ionophores for specific ions, including neodymium and thulium, as well as the application of machine learning models to improve the calibration and accuracy of sensor arrays for environmental analysis.
