In this paper, the electrochemical behavior of ethyl ferulate was investigated by cyclic voltammetry on glassy carbon electrode, and a sensitive electroanalytical method was proposed for its determination. It was shown that, in acetate buffer, the electrochemical behavior of ethyl ferulate has a good reversibility, and the currents of cathodic and anodic peaks had linear relativity with the square root of the potential scan rate, showing that ethyl ferulate presents diffusibility. The electron transfer number n and the diffusion coefficient Do were calculated to be 2 and 1.79 × 10~(-6) cm~2 s~(-1) respectively. Both the cathodic and anodic peak potentials of ethyl ferulate were linearly correlative with pH value of acetate buffer, indicating that proton was involved in the electrochemical process of ethyl ferulate and the numbers of electron transfer and proton were equal. Also, it was observed that both the cathode and anode peak currents are well rectilinear to the concentration of ethyl ferulate in the range of 2.0 × 10~(-7) to 4.8 × 10~(-6) mol L~(-1) (r = 0.9994 and 0.9991, respectively, to the cathode and anode currents, n=8), and the detection limit is 1.0 × 10~(-7) mol L~(-1).
