采用电沉积方法制备六氰合铁酸铜钴-多壁碳纳米管复合修饰电极(CuCoHCF-MWCNTs/GCE).研究碳纳米管用量、电解液组成对该修饰电极性能的影响.结果表明,与单一的六氰合铁酸铜钴薄膜修饰电极相比,六氰合铁酸铜钴-多壁碳纳米管复合修饰电极具有更优良的电化学特性,以其催化氧化过氧化氢,峰电流与过氧化氢浓度在3.16×10-5～2.92×10-3mol·L-1范围内呈良好的线性关系,线性回归方程为ip(μA)=0.5529+1.1299C(×10-4mol·L-1),相关系数r=0.9966,检出限为1.75×10-5mol·L-1.
The electrodeposited CuCoHCF-MWCNTs / GCE composite electrode was prepared by electrodeposition method.The effects of the amount of carbon nanotubes and electrolyte composition on the performance of the modified electrode were investigated.The results show that Compared with the single electrode of copper-cobalt hexacyanoferrate modified electrode, the copper-cobalt hexacyanoferrate composite electrode with multi-walled carbon nanotubes modified electrode has more excellent electrochemical properties. With its catalytic oxidation of hydrogen peroxide, the peak current and The concentration of hydrogen peroxide in the range of 3.16 × 10-5 ~ 2.92 × 10-3mol·L-1 showed a good linear relationship, the linear regression equation was ip (μA) = 0.5529 + 1.1299C (× 10-4mol·L-1 ), The correlation coefficient r = 0.9966, the detection limit of 1.75 × 10-5mol·L-1.
