abstract = "This work aims to demonstrate the importance of coupling different
degradation processes for the removal of the commercial herbicide
Halosulfuron-Methyl (HSM). Using anode oxidation (AO) on
boron-doped diamond as the base process; cathodically produced
H2O2 (AO/H2O2), UV light (AO/UV), AO/UV/H2O2, electro-Fenton and
photoelectron Fenton (PEF) are employed as hybrid processes for
HSM degradation. All hybrid processes employed in the study
exhibited synergism with AO, and the UV-irradiated processes
presented an outstanding performance. In particular, the
AO/UV/H2O2 process exhibited 90 % mineralization after 3 h of
treatment, whereas the PEF process exhibited a complete removal of
HSM after 45 min of treatment. In addition to the noticeable
advantages of hybridization, the application of higher current
densities is found to accelerate the degradation/mineralization of
the compound of interest, although the process tends to be more
energy demanding. In such a case, the use of a hybrid treatment
process coupled to UV-irradiation allows one to mitigate this
constraint while contributing toward obtaining higher
mineralization degrees. The degradation/mineralization of more
concentrated solutions is, however, found to occur more sluggishly
under the treatment mechanisms investigated here, requiring longer
times, although the process is noticeably more efficient in
photo-irradiated processes, which recorded current efficiencies of
above 100 %.",
