“…However, these molecules are very complex and there is a need for further investigations in order to determine the conditions in which these processes can be optimized. Electrolysis is very efficient when the concentration of organics is in the range of 10 3 -10 4 ppm, and the concentrations of antibiotics in urine are much lower; thus, improved knowledge about the mechanisms and possible synergies with other technologies (such as photo-or sono-processes) could help the development of future processes which are capable of solving the problem efficiently [28][29][30][31].…”

In this work, the electrolysis, photoelectrolysis and sonoelectrolysis with diamond electrodes of amoxicillin (AMX) and ampicillin (AMP) solutions were studied in the context of the search for technologies capable of removing antibiotics from liquid wastes. Single-irradiation processes (sonolysis and photolysis) were also evaluated for comparison. Results showed that AMX and AMP are completely degraded and mineralized by electrolysis in both chloride and sulfate media, although the efficiency is higher in the presence of chloride. The effect of the current density on mineralization efficiency is not relevant and this may be related to the role of mediated oxidation. Irradiation by ultraviolet light or ultrasound (US) waves does not produce a synergistic effect on the mineralization of AMX and AMP solutions. This indicates that the massive formation of radicals during the combined processes can favor their recombination to form stable and less reactive species.

“…In contrast, a non-active anode favors the formation of physisorbed M( • OH) that leads to the electrochemical mineralization of organics. By using this approach, the treatment of synthetic and real drug solutions by EO with SnO2 doped with Sb [13,14] and boron-doped diamond (BDD) [11,[15][16][17] has been reported. BDD thin-film electrodes deposited onto p-Si, Nb or Ti show the highest overpotential for O2 evolution and the low adsorption enthalpy of BDD-• OH allows the production of larger amounts of reactive BDD( • OH) compared to other anodes, thereby yielding the most effective mineralization of organic pollutants.…”

“…1) [14]. H 2 O → • OH + H + + e - [1] CDEO has been tested for the treatment of different industrial wastewater [15][16][17] and the removal of several types of pollutants, such as: antibiotics, hormones, among others [18][19][20][21][22][23]. Recently, due to the outstanding results obtained in the treatment of these types of wastewater, CDEO has been used for disinfection processes, reaching high efficiencies [24][25][26][27].…”

In this work, the depletion of a commercial formulation of the pesticide glyphosate (RoundUp) using photolysis, electrolysis and photo-electrolysis with diamond anodes was studied. Results show that single photolysis is an inefficient technology for the removal of the pesticide; however, when coupled with electrolysis the removal yield significantly improves. The use of a combined process (photo-electrolysis) leads to the generation of higher concentrations of free radicals from the photo-activation of the oxidants electrogenerated. A major finding is that the supporting electrolyte plays a key role on the removal of glyphosate due to the generation of different oxidant species. Such species (peroxocarbonates, peroxosulfates and hypochlorite) also contribute to the depletion of the pesticide. Furthermore, the removal of glyphosate is clearly influenced by the current density because of the strong relationship between this parameter and the oxidants produced on the anode surface.
