Abstract

A new ion selective electrode of liquid polymeric membrane, using 5-(4- dimetilamino) bencilidenoRhodanine as ionophore, diocthylphthalate as plasticizer and Poly (vinyl chloride) as matrix was applied in the determination of Ag+ and Vitamine B1, using method potentiometry. The ISE development presented nernstian response slope for Ag+ ions over a wide concentration range with a detection limit of 9,77 · 10-7 mol.dm-3 and exhibited good reproducibility.
Keywords: silver I-selective potentiometric sensor; Ion-selective electrode (ISE).
