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.
