A novel graphene oxide(GO) doped poly(hydroxymethylated-3,4-ethylenedioxythiophene)(PEDOTM)film has been achieved via one-step co-electrodeposition and utilized for electrochemical studies of indole-3-acetic acid(IAA).The incorporation of GO into PEDOTM film facilitated the electrocatalytic activity and exhibited a favorable interaction between the PEDOTM/GO film and the phytohormone during the oxidation of IAA.Under optimized conditions,differential pulse voltammetry and square wave voltammetry were used for the quantitative analysis of IAA,respectively,each exhibiting a wide linearity range from 0.6 μmol L~(-1) to 10 μmol L~(-1) and 0.05 μmol L~(-1) to 40 μmol L~(-1),good sensitivity with a low detection limit of 0.087 μmol L~(-1) and 0.033 μmol L~(-1) respectively,as well as good stability.With the notable advantages of a green,sensitive method,expeditious response and facile operation,the as-prepared PEDOTM/GO organic-inorganic composite film provides a promising platform for electrochemical studies of IAA.
