Abstract

Considering the environmental and health impacts brought on by the presence of antibiotics in the environment, especially in waterbodies / water streams, this project has the specific aim of investigating the influence of different anode materials on the electrochemical degradation of a fluoroquinole antibiotic (contained in an aqueous supporting electrolyte), with identification/determination of the degradation products. The possible application of the best-attained electrolysis conditions to a solution that simulates the low concentration of the antibiotic in a waterbody / water stream or in the influent/effluent of a sewage treatment plant will be also investigated.
