A simple and environment-friendly electrochemical method using activated glassy carbon electrodes (aGCE) for monitoring the residues of tetracycline in pork samples was developed. A two-step pretreatment procedure was established for activating the glassy carbon electrode surface, including mechanical polishing and electrochemical pretreatment. In the supporting electrolyte solution of 0.2 M sodium sulfate (at pH 2.5), the electrochemical response of TC was characterized by two irreversible oxidation peaks at +0.95 V and +1.05 V vs. saturated calomel electrode.
