| Abstract: | A new polymeric membrane iodide selective electrode based on Schiff base Complex derived from PMBP with thiocarbohydrazide as neutral carrier is developed. The electrode exhibits Nernsitan potential liner range to nitrite ion from 3.0×10-2 to 7.5×10-5mol/L with a slope of -56.3mV/dec NO2- in pH 2.0 phosphate buffer solution. The electrode has the advantages of simplicity, fast response, fair stability and reproducibility. |
