Cd(II) PVC-Based Membrane Sensor Based on N′-[1-(2-furyl)methylidene]-2-furohydrazide
Abstract:The N′p-[1-(2-furyl)methylidene]-2-furohydrazide was used as an excellent ionophore in the construction of a Cd(II) PVC-based membrane sensor. This sensor demonstrated good selectivity and sensitivity towards the cadmium ion for a broad variety of cations, including alkali, alkaline earth, transition and heavy metal ions. The sensor also revealed a great enhancement in selectivity coefficients for cadmium ions, in comparison with the formerly mentioned cadmium sensors. In detail, the suggested sensor exhibited a Nernstian behavior (with a slope of 29.4 ± 0.5 mV per decade) over the range of 1.0 × 10−6–1.0 ×10−1 M with a detection limit of 7.3 × 10−7 M (82.06 g/L). The response time was relatively quick in the whole concentration range ( < 10 s). The sensor usage was found to be at least 9 weeks in a pH range of 2.8–8.6. As a result, the developed sensor was successfully applied to the direct cadmium ion determination in solution and as an indicator electrode in the Cd(II) ion potentiometric titration with EDTA.
