“…They are also use in development of photonic devices and have potential applications such as metallomesogens [12]. However, despite extensive applications of these ligands and many reports on synthesis and characterization of the Schiff base ligands and their complexes, there are a few reports on their ion-selective studies [13][14][15][16]. Moreover, it seems that Schiff base ligands are suitable ionophores for preparation ion selective electrodes and determination of many metal ions [17,18].…”

An ion selective potentiometric electrode (IPE) was prepared based on salen material (bis(salicylaldehydo)ethylenediimine) as a suitable carrier for determination of cadmium ions. An acceptable response for cadmium ions obtained over a linear range 8 × 10−7 to 1.0 × 10−2 M with a slope of 29.8 ± 0.8 mV per decade of activity and a detection limit of 3.2 × 10−7 M for Cd (II) ions in water and liquid samples. It has a response time less than 10 s and can be used for at least 2.5 months without any measurable divergence in potential. The ion selective electrode can be used based on potential and potential changes in the pH range 3.5 to 6.5, so, the cadmium determination was obtained at independent pH. Moreover, the selectivity of proposed method in presence of interference ions was studied. The results showed that the other cations do not interfere significantly in response electrode at optimized pH. This electrode was successfully used for the determination of cadmium ions in aqueous samples. The validation was obtained based on ICP analyzer and certified reference material in water samples (CRM, NIST).

“…In 2010, Hernandez et al described determination of calcium ions in sap using carbon nanotube-based ionelectrode. Recently, a new simple, highly specific and calcium selective electrode has been prepared by Vijayalakshmi and Selvi (2017). This calcium selective electrode was also successfully used in the analysis of concentration of Calcium ion in various real samples (Vijayalakshmi and Selvi, 2017).…”

Ion-selective electrode (ISE) is a useful tool in the direct determination of ionic species in complex samples. This study relates to the manufacture of Ca 2+ -selective electrode with single-barrelled microelectrodes and an internal filling solution buffered for pCa (pCa= -lg[Ca 2+ ]) of 6. It is shown that an improved lower detection limit of 10 -6 M is obtained in Ca 2+ buffer solution and the changes in electromotive force between two solutions of 10-fold change in Ca 2+ concentration are close to 30 mV/decade.
