中文摘要：
本文应用了一种方便有效的方法制备了碳纳米管四氧化三铁复合物（CNTs／Fe3O4）修饰电极，并在修饰电极干燥过程中应用了磁场。这种在磁场作用下制备的修饰电极对多巴胺（DA）表现出很强的电催化活性。采用了X射线衍射（XRD）、透射电子显微镜（TEM）对制备出来的碳纳米管四氧化三铁复合物的组成、形貌和结构进行了表征。扫描电子显微镜（SEM）对修饰电极的表面形貌进行了表征，循环伏安法（CV）和示差脉冲伏安法（DPV）对修饰电极的电化学性能进行了表征。实验表明，该电极对多巴胺的电化学氧化具有明显的催化作用。用DPV对多巴胺进行了测定，其氧化峰电流与多巴胺的浓度在6．0×10^-7-4．3×10^-4mol·L^-1范围内呈良好的线性关系，线性相关系数为0．9989，检出限（S／N=3）为3．2×10^-8mol·L^-1。
