摘　　要：以铂电极为基体,用电沉积方法制备了铁氰化钴修饰电极,研究了该电极的电化学特性及H2O2在该修饰电极上的电化学行为。实验表明,该电极对H2O2具有催化作用;在4.9×10-5～1.1×10-3mol/L范围内,峰电流与H2O2的浓度呈线性关系(R=0.9986),检出限为1.3×10-5mol/L。A modified electrode was prepared by using cobalt hexcyanoferrate as modified membarane based on platinum.The electro-chemical properties of the electrode and electro-chemical behaviors were studied.The results showed that cobalt hexcyanoferrate modified platinum electrode had catalytic effect on H2O2,The peak current of H2O2 on the electrode increased linearly with the concentration of H2O2 between 4.9 × 10^-5 1.1 × 10^-3mol/L.The detection limit was 1.3 × 10^-5mol/L.
