Potentiometric and Ion-Selective Electrode Sensors for Water and Environmental Analysis
This community develops electrochemical devices that detect specific ions in liquid samples, primarily for monitoring water quality, environmental contamination, and biological fluids.
The work centers on the design and optimization of ion-selective electrodes (ISEs) and potentiometric sensors. Recurring materials include PVC membranes, iridium oxide, carbon nanotubes, and graphene oxide, often integrated into solid-contact configurations to improve stability and sensitivity. The research also heavily features field-effect transistors (FETs) and extended-gate FETs for transducing ion concentration into electrical signals. Applications are dominated by the determination of potassium, sodium, and heavy metal ions in water samples, with a significant focus on high selectivity and sensitivity for environmental and biomedical testing.
The community’s output is most concentrated in research tracked for chlorine, representing 0.6% of all chlorine research, and potassium, representing 0.4% of all potassium research. It also contributes 0.3% of silver research.
The community comprises 8,011 papers, published most frequently in Analytica Chimica Acta, Analytical Chemistry, and Talanta.
Recent work continues to focus on the development of solid-contact potentiometric sensors for specific ions like sodium and copper, as well as flexible and printed sensor technologies for pH monitoring and heavy metal detection in environmental and food safety applications.
