abstract
an iodide ion-selective pvc membrane sensor based on copper (π)-bis-nphenilsalicyldenaminatocomplex as a novel sensing material is successfully developed. theelectrode showed a good selectivity for iodide ion with respect to common inorganic anions. thesensor exhibited a good linear response with slope of _58.6 ± 0.4 mv per decade over theconcentration range of 5.0 × 10-6 to 1.0 × 10-1 mol l-1, and a detection limit of 3.0 × 10-6 mol l-1of i– ion. the electrode response was independent of ph in the range of 3.0 - 10.0. the proposedsensor was applied as an indicator electrode in potentiometric titration of i– with ag+ ion, and todetermine the iodide in sodium chloride salt.

A highly selective PVC membrane electrode based on a cerium-salen complex was prepared. The sensor displays an anti-Hofmeister selectivity sequence with a preference for iodide ion over many common organic and inorganic anions. The proposed electrode exhibits a near-Nernstian behavior over a wide concentration range (5.0 x 10(-2) - 8.0 x 10(-6) M) with a slope of 57.5 mV per decade, and a detec...

In this work we introduce a practical use of synthesized Schiff base metal complex in sensing application. A new perchlorate-selective electrode based on the complex N, N'-4-nitro-phenylmethanebis-(salicylaldiminato) copper (II) [CuL] as the membrane carrier was developed. The electrode exhibits a good Nernstian slope of -55.0 ± 1.0 mV/decade and a linear range of for perchlorate. The lim...
