Abstract: Anew type of polymeric membrane iodide selective electrode based on bisbenzoylacetone-ethylenediiminocobalt(Ⅱ) as the carrier has been prepared.It gives linear response over the concentration range 1.0×10-1-2.0×10-6 mol/Land a response slope of 57.1±0.3mV/pI(at 20℃).The electrode is fairly selective for iodide over perchlorate, thiocyarate and salicylate.The response mechanism has been investigated.The a.c.impedance spectra and other characteristics of the electrode were also studied.

Key words: Carrier, Bisbenzoylacetone-ethylenediiminocobalt(Ⅱ), Iodide selective electrode
