摘　　要：制备了 PVC-丁二酮肟修饰电极 ,研究了膜电极的响应过程和钯在此电极表面的伏安特性。用微分脉冲伏安法测定 ,钯在 4.76× 1 0 -9mol/ L～ 9.53×1 0 -8mol/ L 的浓度范围内 ,电流与浓度的对数成线性关系 ,检出限为 1 .52×1 0 -9mol/ L。此法可用于矿样中钯的测定。A PVC dimethylglyoxime coated glass carbon electrode was prepared. The differential pulse voltammetry (DPV) of Pd(Ⅱ) on the electrode was studied.A linear calibration graph was obtained in the range of 4.76×10 -9 ～9.53×10 -8 mol/L with detection limit of 1.52×10 -9 mol/L for Pd(Ⅱ). The method was applied to the determination of palladium in minerals.
