Voltammetric detection of tetracycline in water at borondoped diamond electrode

In this work, a voltammetric-based protocol for the detection of tetracycline (TC), considered an emergent pollutant in water, was developed. The electrochemical behavior of TC studied by cyclic voltammetry was considered to optimize operating conditions of advanced voltammetric techniques, e.g., differential-pulsed voltammetry (DPV) and square-wave voltammetry (SWV). The best electroanalytical parameters for TC detection of 2,29 µA/µM sensitivity and limit of detection (LOD) were achieved using SWV under SP of 0.05V, MA of 0.1V, and frequency of 10 Hz.
