The electrochemical determination of ferulic acid was carried out with highly sensitive and rapid square wave voltammetry (SWV) and cyclic voltammetry (CV) techniques by using bare glassy carbon electrode and carbon mesoporous fabricated glassy carbon electrode (CMP/GCE). The oxidation kinetics of ferulic acid was studied after the experimental conditions were optimized. A voltammetric study of ferulic acid at the CMP/GCE electrode exhibited a well-defined anodic peak in phosphate buffer at pH 2.2. The square wave oxidation peak current of ferulic acid was linearly increased over the concentration range from 1 to 7 μg mL^-1. The LOD and LOQ for ferulic acid were calculated as 0.36 and 1.10 μg mL^-1, respectively. The analytical application of the developed sensor was evaluated by a real sample analysis of ferulic acid in sweet corn.
