Construction of a novel Cu(II)-selective electrode with long life span based on 8-aminoquinoline functionalized bentoniteDogan, BilgeColdur, FatihCaglar, BulentOzdemir, Agah OktayGuner, Eda KelesOzdokur, Kemal Volkan8-AminoquinolineCarboxylated PVCCopper(II) detectionFunctionalized-bentonitePotentiometric electrodeA novel 8-aminoquinoline-functionalized bentonite was utilized as an electroactive sensing element in the construction of a potentiometric carboxylated-PVC-based polymeric membrane electrode. The electrode exhibited a linear response for copper(II) ions in the concentration range of 1.0 × 10–5−1.0 × 10–2 mol/dm3 with a slope of 28.24 mV/decade. While the response time of the electrode determined as about 20 s, its detection limit and long life time was determined as 5.0 × 10–6 mol/dm3 and 5 months, respectively. The proposed electrode was applied for the potentiometric detection of Cu(II) contents of some spiked water samples and satisfied results were attained.
