Er۳+-PVC Membrane Sensor Based on ۳-hydroxy-N'-((pyridin-۲-yl)methylene)naphthalene-۲-carbohydrazide

Erbium has no biological role but is said to stimulate the metabolism All erbium compounds should be regarded as highly toxic, although initial evidence would appear to suggest that the danger is limited [۱]. Solvent polymeric membrane based ISEs, together with the incorporation of ion carriers, have shown to be a very useful tool for clinical, environmental, and chemical analyses as well as for process monitoring. Potentiometric detection based on ion-selective electrodes (ISEs) offer the advantages of speed and ease of preparation and procedures, relatively fast response, reasonable selectivity thorough judicious choice of the membrane active materials, wide linear dynamic range, and low cost [۲,۳]. In this research, we wish to report the preparation a Er۳+ PVC-based membrane electrode based on ۳-hydroxy-N'-((pyridin-۲-yl)methylene)naphthalene-۲-carbohydrazide (L) as an neutral ion carrier.
