عنوان انگلیسی A Simple Electrochemical Method to Detect Tetracycline in Honey Samples using Electrochemically Activated Glassy Carbon Electrode in Surfactant Medium
چکیده انگلیسی مقاله An electrochemical method for the determination of tetracycline has been reported, employing cyclic voltammetry (CV) and differential pulse voltammetry (DPV) techniques with an activated glassy carbon electrode serving as the working electrode. In the presence of a suitable surfactant, the peak current enhancement of tetracycline was achieved. The interference effects and their elimination of the electrochemical method were also studied in the presence of various ions. The current responses obtained under the optimum experimental conditions through the DPV technique of tetracycline increased linearly with concentrations in linear dynamic ranges of 1.0 - 10 μmol L-1 and 10 - 100 μmol L-1 with 0.31 μmol L-1 detection limits. Combined with solid-phase extraction (SPE), the proposed method was effectively used for the determination of tetracycline residues in honey, achieving recovery rates ranging from 81.8% to 91.8%. The results suggest that this method is applicable for the detection of TC in complex food matrices.
