Özet:

 

All solid-state contact poly vinyl chloride (PVC) membrane  potassium-selective electrode has been developed.  The construction of  the ion selective electrode membrane was organized using ionophore  4,4'-bis[4''-phenoxy(15-crown-5) methyl]benzyl in PVC cocktail.  The  potentiometric performance characteristics of the electrode were  investigated by a computerized system.  The electrode was found highly  selective to K+ ions over a wide variety of other cations.  The  electrode almost exhibited a Nernstian response (\ge 55 (\pm15)  mV/decade of K activity) to K+ within the concentration range 1.5  x 10-1 - 1.0 \times 10-5 M. The operational pH range of the  electrode was 5--7.  The response time of the electrode was fast (.
