A copper(Ⅱ) Schiff base complex with ethylene-diamine-bis-(salicylaldehyde)[Cu(Ⅱ)-EDBSAD] was synthesized and a poly vinyl chloride(PVC) membrane electrode with the complex as neutral carrier was prepared.The electrode displays a preferential potentiometric response to SCN-and exhibits near Nernst response for SCN- within a wide concentration range(1.0×10-1~1.0×10-7 mol/L) with calibration curve equation of E(mV)=-51.75lg cSCN--255.29,and a detection limit of 5.6×10-8 mol/L in pH=5.5 phosphate buffer solution at 25℃.This electrode was applied to the determination of SCN- in waste water and the obtained result was in good agreement with those of high-performance liquid chromatography method.
