Iodide Selective Electrode Based on Cobalt(Ⅱ) Complex with Dual-core Schif Base as Neutral Carrier

摘要：

　　A new highly selective poly vinyl chloride(PVC) membrane iodide electrode which has neutral carrier of cobalt(Ⅱ) complex with symmetrical binuclear schiff base has been studied.Based on the fact we knew that ethylenediamine could react to acetylacetone and salicylaldehyde.The electrode exhibited near-Nernst response to iodide with a slope of —54.4 mV/dec over a wide concentration range (1.58×10-7~1.0×10-1mol/L) with a detection limit of 6.3×10-8 mol/L in phosphorate bufer solution with pH=2.4 at 26℃.After applied to the determination of iodide in pharmaceuticals and salts,the electrode could get satisfied results
