Polymeric Membrane Sensors for Detection of Cesium (I), Chromium (III) and Titanium (III) Ions Based on Calixarene Ionophores

Ion selective electrodes (ISEs) allow the potentiometric sensing of the activity of specific ions in the presence of other ions in aqueous and non-aqueous solutions. ISEs are invaluable tools for continuous monitoring and can be used in environmental, agricultural, industrial and clinical fields. T...
