'In-situ' antimony film electrode for the determination of tetracyclines in Argentinean honey samples

Abstract

The main goal of this work is the application of an antimony film electrode (SbFE) prepared for thefirst time ?in-situ? to determine organic compound as tetracyclines commonly used in Argentine forhive treatment. The SbFE was prepared on a glassy carbon electrode (GCE) and square wave cathodicstripping voltammetry (SWCSV) technique was used. The SWCSV parameters were optimized based on aDraper Lin small composite design. The SWCSV response was linear in the TCs concentration range from0.40 to 3.00 uM with a limit of detection (LOD) of 0.15 uM. The proposed method is a good and simplealternative to the determination of tetracyclines in Argentinean honeys samples. Recovery experimentswere performed using spiked honey samples with standard deviation values from 0.75% and 9.69%.
