ABSTRACT:
The preparation of silver ion selective polymer membrane and its application to ion selective electrode is reported here. PVC membrane contains silver selective N, N’ [1, 1’-dithiobis (phenyl)]bis(5’methoxysalicyl-aldimine) (5-MeOSalps) as ionophore. The sensor possess a nernstian slope of 58.20 ± 0.5 mV per decade over a wide linear concentration of 1.0 × 10-1 to1.0 × 10-6 M with a detection limit of 5.0 × 10-6 M. The electrode response is stable over wide pH range of 4.5 -10.5. It has a fast response time of 5 s and can be used for more than 5 min. without any considerable change in potential. The proposed electrode shows good selectivity over a variety of alkali, alkaline earth and transition metal ions.
