The iodide ISE consists of a solid-state membrane selectively permeable to iodide ions and an internal reference electrode. When immersed in a solution containing iodide ions, an electrical potential is generated, which can be measured to determine the iodide ion concentration. This electrode is particularly useful in applications such as environmental monitoring, pharmaceuticals, and food analysis, where iodide levels are critical.

Tips: What are the iodide ISEs commonly used for?

Iodide ion-selective electrodes (ISEs) are commonly used for measuring iodide concentration in various analytical applications. These electrodes are particularly valuable in titrations, where they determine the endpoint of reactions involving iodine or iodide. Iodide ISEs are extensively employed in pharmaceutical, environmental, and food industries for quality control and research purposes. They find applications in iodometric titrations, detecting trace amounts of iodide in solutions, and monitoring iodide levels in samples like biological fluids. The sensitivity and selectivity of iodide ISEs make them crucial in studies related to iodine metabolism, thyroid function, and the determination of iodine content in different matrices. Their use extends to fields such as clinical chemistry, water analysis, and food testing, contributing to accurate and efficient iodide concentration measurements in diverse samples.
