摘　　要：合成了双水杨醛缩乙二胺合铜(Ⅱ)[Cu(Ⅱ)-EDBSAD]席夫碱金属配合物,并以该配合物为中性载体制备PVC膜电极,该电极对SCN-具有优良的电位响应特性,在pH=5.5磷酸盐缓冲溶液中,SCN-浓度在1.0×10-1～1.0×10-7mol/L之间具有能斯特响应,校准曲线方程为E(mV)=-51.75lg cSCN--255.29,检测下限为5.6×10-8mol/L。将电极用于废水中硫氰酸盐含量的测定,结果与高效液相色谱法基本一致。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（1.0×10-1～1.0×10-7mol/L） with calibration curve equation of E（mV） = -51. 751g 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.
