Abstract

The macrocyclic ligand, 15-crown-5, was used as an ionophore for fabrication of a polyvinyl chloride (PVC) based membrane sensor for Ag(I) cation. For construction of the Ag(I) cation selective electrode, the best response characteristics were obtained using the composition: 15-crown-5/PVC/o-nitrophe- nyloctylether (NPOE)/sodium tetraphenyl borate (NaTPB) in the percentage ratio of 5.6/30/60.5/3.9 (w/ w/w/w). The electrochemical sensor shows a linear dynamic range 1.0 _ 10_7–1.0 _ 10_1 mol/L and a Nernstian slope of 58.9 _ 0.5 mV/decade with a detection limit of 8.09 _ 10_8 mol/L for Ag(I) cation. It has a fast response time of <10 s and can be used for at least 8 weeks without any considerable divergences in its potential response. It was successfully used as an indicator electrode in potentiometric titration of Ag(I) cation with I_ and Cl_ anions and also for the determination of this metal cation in radiology waste water.
