摘要

以碳纳米管（MWNTs）修饰的碳糊电极为基底电极,通过电沉积方法制备了六氰合铁酸钴（CoHCF）纳米多孔生物传感平台。考察了MWNTs对CoHCF沉积的影响,优化了CoHCF沉积的各种实验条件(0.5 mol/L KCl,1 mmol/L CoCl2和0.9 mmol/L K3Fe(CN)6混合溶液，在循环伏安电压范围0~1.1 V内扫20圈，扫速100 mV/s),借助循环伏安法、交流阻抗法和扫描电镜法对修饰电极进行了表征。由于MWNTs的支撑作用,电沉积得到的CoHCF呈现出多孔结构和良好的电化学稳定性。具有纳米多孔结构的MWNTs-CoHCF薄膜能有效地促进生物小分子在电极上的电子交换,维生素B2在纳米多孔CoHCF/MWNTs上具有优异的氧化还原行为,其测定线性范围为1.2×10-7~2.6×10-7 mol/L,检出限为8.9×10-8 mol/L。

Abstract

A cobalt hexacyanoferrate（CoHCF） film was successfully electrodeposited on functionalized multi-wall carbon nanotubes（MWNTs） modified glassy carbon electrodes by scanning the potential between 0 V and 1.1 V at a scan rate of 100 mV/s for 20 consecutive scans in an aqueous electrolyte of 0.5 mol/L KCl, 1 mmol/L CoCl2 and 0.9 mmol/L K3Fe(CN)6.The modified electrodes （MWNTs-CoHCF/GCE） were characterized by scanning electron microscope and cyclic voltammetric methods.It was found that the CoHCF film was covered with the MWNTs.The MWNTs-CoHCF/GCE presented a nanoporous structure with an excellent electrochemical stability,which showed a favorable electron transfer kinetics.The cyclic voltammetric experiment showed that the MWNTs-CoHCF/GCE had a favorable electrochemical activity for the oxidation of vitamin B2 （VB2）,and the peak current was linear over VB2 concentration in the range of 1.2×10-7-2.6×10-7 mol/L with a detection limit（S/N=3） of 8.9×10-8 mol/L.
