表面活性剂对普鲁士蓝复合修饰电极性能的影响

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.%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.
