中文摘要：

使用滴涂的方法制备多壁碳纳米管（MWNTs）修饰电极（MWNTs/GCE）,并利用循环伏安法在该电极表面沉积普鲁士蓝（PB）,从而得到普鲁士蓝-多壁碳纳米管复合修饰电极（PB/MWNTs/GCE）,相对于相同条件下在裸玻碳电极表面制备的PB修饰电极,该电极表现出更优良的电化学性质。通过使用不同性质的表面活性剂对MWNTs进行分散,制备了系列MWNTs基PB修饰电极,并研究了表面活性剂对PB复合修饰电极性能的影响。实验结果表明,表面活性剂的加入提高了PB/MWNTs/GCE基修饰电极对过氧化氢的检测范围。

英文摘要：

Multiwall carbon nanotubes （MWNT） modified glassy carbon elelctrode（GCE） was prepared by dropping method. Under the same condition, the resulting electrode （PB/MWNTs/GCE） behaved better electrochemical characterization than PB/GCE. The surfactants with different properties have been used to scattered the MWNTs. A series of Prussian Blue-MWNTs based modified electrode with surfactants have been prepared. The electrochemical results demonstrated that the added surfactants widened the linear range of electrodes for detection of H2O2.
