Abstract Two types of zeolite-modified electrodes, e.g., Ag-doped zeolite-expanded graphite-epoxy (AgZEG) and Cu-doped zeoliteexpanded graphite-epoxy (CuZEG) composite electrodes were tested for the application of the electrochemical determination of 4-aminophenol (4-AP). The electrochemical techniques used for the electrochemical determination of 4-AP were cyclic voltammetry (CV) and chronoamperometry (CA). Some aspects related to the mechanistic behaviour are discussed. The electrochemical determination of 4-aminophenol on AgZEG and CuZEG composite electrodes was achieved in the concentration range 0.05 to 0.4 mM, with a sensitivity of about 0.2 mA*cm-2*mM-1. The electroanalytical performance of the determination of 4-AP on zeolite-modified electrodes was not influenced by the type of electrode.
