Spectroscopic studies showed a selectivity of a new organic compound (L) toward copper ions and several transitional metal ions. Hence, L was utilized in designing several ion selective electrodes for these cations. In practice, Cu2+ ion selective electrode behaved Nernstian (slope of 27.95±0.3 mV decade-1) over a wide linear range of 1.0×10-6-1.0×10-2 mol L-1. Optimum performance of the indicator electrode was observed by a membrane containing 7% selectophore, 2% sodium tetraphenyl borate (NaTPB) as an ionic additive, 61% nitrobenzene (NB) as solvent mediator and 30% polyvinyl chloride (PVC). The sensor showed a short response time of about 20 s and an acceptable life time, the potentiometric response is independent on the pH of the solution in the range of 3.5-7. The optimized copper sensor was used for analysis of copper content of some blood plasma samples. The obtained results were in good agreements with ICP-OES method.}, keywords = {copper,Selectophore,sensor,Potentiometry,Ion selective electrode}, url = {https://www.abechem.com/article_43211.html}, eprint = {https://www.abechem.com/article_43211_e049542f179031c8e94b9998e5a43f14.pdf} }
