摘　　要：报道聚苯胺修饰电极制备中尚须引起人们重视的几个问题。主要包括：循环伏安法扫描电位上限对聚合的影响，恒电位法最佳的聚合电位，以及仅具２００ｍＶ和９００ｍＶ两峰聚苯胺膜的制备，聚合电量对不同制备方法影响的差异性等等。并对制备聚苯胺修饰电极的几种方法进行了比较，从而指出了最佳的聚合方法和条件。Several affairs that have not been given much at-tention to in the preparation of polyaniline modifiedelectrodes were reported in this paper.The affairsmainly included the effect of the upper scanning po-tential on the polymerization when using the methodof cyclic voltammetry,the best potential employedwhen using the method of potentiostatic,the prepara-tion of the polymer that has only two peaks at 200mV and 900 mV in CV figure,and the effect of elec-tric quantity on the methods of the polymerization,etc,The methods being used in the preparation ofpolyaniline modified electrodes were also compared sothat thebest metho6and conditions were pointed out.
