Search for new ionophores and determination of trace levels of Cu2+ ions by potentiometric ion–selective electrodes

Abstract

Copper(II) ions are essential at trace levels but become toxic at elevated concentrations, making their rapid and accurate determination in environmental samples highly important. This letter reports the performance of ionophore molecules synthesized by our research group for the potentiometric detection of Cu2+ using ion–selective electrodes. The developed sensors showed fast response, good selectivity, low detection limits, and simple operation, and were successfully applied to environmental samples. In addition, the use of newly designed ionophores offers a cost-effective alternative to commercial counterparts, reducing overall sensor fabrication costs while maintaining satisfactory analytical performance.
