چکیده مقاله:
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...
