【摘要】 制备了普鲁士蓝(PB)/壳聚糖(CS)/多壁碳纳米管(MWCNTs)修饰的玻碳电极。采用循环伏安法(CV),扫描电子显微镜、红外光谱技术对修饰电极进行表征,结果表明,PB纳米成功的修饰到电极表面,膜结构较均一,修饰量大,具有较强的空间结构性。此外,研究了不同pH值和不同扫描速率条件下PB/CS/MWCNTs修饰电极在0.1mol/L磷酸缓冲溶液中的电化学行为,结果表明该修饰电极具有良好的电化学性质,在电化学生物传感器领域具有潜在的应用价值。更多还原

【Abstract】 A prussian blue(PB)/chitosan(CS)/multiwall carbon nanotubes(MWCNTs) modified electrode was fabricated.Cyclic voltammetry(CV),Scanning electron microscopy(SEM) and Fourier transform infrared spectra(FTIR) were used to characterize the modified electrode.The results indicated that PB nanomaterial could be successfully immobilized onto the surface of the electrode,the membrane structure was uniform,and the modifying quantity was big with strong space structure.In addition,the effect of pH and scanning rate on the electrochemical behaviors of the PB/CS/ MWCNTs/GCE was investigated in 0.1mol/L phosphate buffer solution.The result showed that the modified electrode exhibited an excellent electrochemical property,which has potential application value for researching electrochemistry biosensor.更多还原
