摘　　要：用循环伏安法(CV)对聚苯胺(PANI)与不同类水滑石(HTlc)逐层滴涂修饰的玻碳电极(GCE)进行了表征。研究结果表明,随HTlc中n(Mg2+)/n(Al3+)变化,修饰电极PANI/HTlc/GCE上Fe(CN)3-6氧化还原峰电流先增加后降低,说明此修饰电极的促电子转移作用受HTlc层板电荷密度的影响。当MgAl-HTlc片层中部分Mg2+、Al3+金属离子被Co2+、Ni2+和Fe3+分别替代后,得到的掺杂HTlc修饰电极均使Fe(CN)3-6的氧化还原电流减小,表明修饰电极的电化学性质与类水滑石的片层组成有关。The electrochemical behavior of PANI/HTIc/GCE electrode （modified glassy carbon electrode by polyaniline （PANI） and hydrotalcite - like compounds （HTlc） ） were investigated, using cyclic voltammetry （CV） method and Fe（ CN）6^3-probe. The reduction current and oxidation current first increased and then decreased as the n （ Mg2＋ ）/n （ Al3＋ ） of HTlc layer increasing. This showed that the electron transfer was controlled by layer charge density of HTlc. When the metal ions of Mg - Al - HTle layer were partial substituted by Co2＋ , Ni2＋ or Fe3 ＋, the reduction current and oxidation current of Fe （CN） 6^3- were reduced. This result showed that the component of HTIc layer impacted the electrochemistry properties.
