报道了水杨醛肟化学修饰碳糊 ( SAMCP)电极的制备 ,研究了钯 ( )在该电极上的阴极溶出伏安特性。在 p H2 .6的 NH4Cl底液中 ,钯 ( )在 - 0 .78V( vs.SCE)处有一灵敏的阴极溶出峰 ,峰电流与钯 ( )的浓度在 4 .7× 1 0 -8～ 2 .8× 1 0 -5 mol/L之间呈良好的线性关系。当富集 2 min时检测限为 2 .4× 1 0 -9mol/L。本方法已用于阳极泥中钯的测定。
The preparation of salicylaldehyde chemically modified carbon paste (SAMCP) electrode was reported. The cathodic stripping voltammetry of palladium () was studied. In the NH4Cl bottom solution of p H2 .6, palladium has a sensitive cathodic dissolution peak at -0.78 V (vs.SCE) with a peak current and palladium concentration of 4.7 × 10 -8 ~ 2 .8 × 10 -5 mol / L showed a good linear relationship. When 2 min enrichment, the detection limit was 2.4 × 10 -9 mol / L. This method has been used for the determination of palladium in anode slime.
