1,3,4-Trisubstituted-2-azetidinone Derivatives asNovel Receptors for Bismuth(III) Ion-SelectiveElectrodes: Application in Pharmaceutical andGlass Samples

摘要

Polymeric membrane electrodes (PM Es) and coated graphite electrodes(CGEs) containing 1,3,4-trisubstituted-2-azetidinone derivatives as ion carriersare reported here for bismuth(III) ion selectivity. These electrodes exhibitedNernstian response for Bi3+ ions over a wide concentration range (5.0 × 10~(-7)Mto 1.0 × 10~(-1)M for CGE) with a lower detection limit of 3.98 × 10~(-7)(forCGE) and wide pH range (1.3-5.0). Compared to polymeric membrane electrode,the coated graphite electrode has shown better selectivity for Bi~(3+)ions withrespect to common metal ions. Proposed electrodes have been used for theestimation of Bi~(3+)ions in pharmaceutical and glass samples.
