摘　　要：研究了电化学方法制备的聚２，５－二甲氧基苯胺薄膜电极（Ｐ２５ＤＭＡｎ／Ｐｔ）对水溶液中儿茶酚的电催化作用，以及影响催化作用的主要因素，结果表明，在酸性较强的水溶液中，在较充的浓度范围内（儿茶酚的浓度为１×１０￣－１～５×１０￣－５ｍｏｌ／Ｌ）均有很好的电催化作用，催化电流与儿茶酚浓度呈良好的线性关系。Poly(2,5- dimethoxyaniline)film was synthesized with the method of electropolymerzation.Instrong acidic solution,the redox reaction of pyrocatechol could well be catalyzed by poly(2,5-dimethoxyaniline)film electrode in a wide range of pyrocatechol concentration.Some important fac-tors which affect electrocatalytic reaction of pyrocatechol at poly(2,5-dimethoxyaniline)film elec-trodes were discussed.The catalytic limiting currents were proportional to concentration of pyrocatecholin the range of l×10￣-1～5×10￣-5mo1/L,and poly(2,5-dimethoxyaniline)was very stable.
