Spanish abstract Este trabajo muestra la degradación de diclofenaco por oxidación electroquímica en medio de NaClO4 y pH neutro empleando el reactor el FM01-LC equipado con un ánodo de diamante dopado con boro (BDD). Se llevaron a cabo estudios de microelectrólisis para determinar el dominio de densidad de corriente donde se favorece la formación de radicales hidroxilo (•OH), 10 ≤ j ≤ 20 mA cm−2. Se realizaron electrolisis a velocidades promedio de flujo comprendidas entre 14.6 ≤ u ≤ 58.4 cm s−1. La degradación completa de diclofenaco (100%) se logró a 15 mA cm−2 and u=29.2 cm s−1, con una eficiencia de corriente de 78% y un consumo de energía de 2.54 kWh m−3
English abstract This paper deals with the degradation of diclofenac by electrochemical oxidation in NaClO4 medium at neutral pH using a FM01-LC reactor equipped with a boron doped diamond electrode (BDD). Microelectrolysis studies were carried out to find the current density domain where hydroxyl radical (•OH) formation is favored, 10 ≤ j ≤ 20 mA cm−2. Electrolysis experiments at mean linear flow velocities of 14.6 ≤ u ≤ 58.4 cm s−1 were performed. The experimental set-up achieved 100% diclofenac mineralization with 78% current efficiency and energy consumption of 2.54 kWh m−3 at j = 15 mA cm−2 and u=29.2 cm s−1
