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 to 1.0×10-6 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.

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 to 1.0×10-6 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.
