摘　　要：以二苯基乙二酮和邻氨基苯酚合成了二苯基乙二酮缩邻氨基苯酚双席夫碱,并将其作为中性载体与碳粉混合,以液体石蜡为粘合剂,制备了Cu(II)离子选择性电极。室温下,该电极对Cu2+呈现近能斯特响应,响应浓度范围为5.0×10-6～1.0×10-2mol/L,斜率为40.14 mV/dec,检出限为2.3×10-6mol/L。考察了10种离子的干扰情况,结果显示,电极对Cu2+具有较好的选择性。With the protection of nitrogen atmosphere, a novel Schiff base compound of 1,2-diphenlethanedione-2-aminophenol, was synthesized. A copper（Ⅱ） ion selective electrode was prepared by using the Sehiff base compound as neutral carrier mixed with car- bon powder and employing liquid paraffin as adhesive. The electrode exhibits Nernstian response to Cu （II）over a range of 5. 0×10-6 ～ 1.0×10-2 mol/L with a slope of 40. 14 mV per decade with a detection limit of 2. 3×10-6 mol/L at room temperature. Results showed that the electrode exhibited a good selectivity for Cu（Ⅱ） over a wide variety of common metal ions.
