Abstract A novel optical chemical sensor (optode) was fabricated for the determination of
silver ions. The optical sensor was prepared by incorporating recently synthesized
ionophore, 7-(1H-benzimidazol-1-ylmethyl)-5, 6, 7, 8, 9, 10-hexahydro-2H-1, 13, 4, 7, 10-
benzodioxatriaza cyclopentadecine-3, 11 (4H, 12H)–dione, sodium tetraphenyl borate
(NaTPB) as an anionic additive, 3-octadecanoylimino-7-(diethylamino)-1, 2-
benzophenoxazine (ETH5294) as a chromoionophore, and dioctyl phthalate (DOP) as a ...
