[Display omitted] •An “in-situ” antimony film electrode to determine tetracyclines was performed.•Highly efficient Draper Lin small composite design was used to optimize parameters.•The method was successfully applied to determine tetracyclines in Argentinean honeys.•Antimony electrodes are an alternative to the use of mercury and bismuth electrodes. The main goal of this work is the application of an antimony film electrode (SbFE) prepared for the first time “in-situ” to determine organic compound as tetracyclines commonly used in Argentine for hive treatment. The SbFE was prepared on a glassy carbon electrode (GCE) and square wave cathodic stripping voltammetry (SWCSV) technique was used. The SWCSV parameters were optimized based on a Draper Lin small composite design. The SWCSV response was linear in the TCs concentration range from 0.40 to 3.00μM with a limit of detection (LOD) of 0.15μM. The proposed method is a good and simple alternative to the determination of tetracyclines in Argentinean honeys samples. Recovery experiments were performed using spiked honey samples with standard deviation values from 0.75% and 9.69%.
