Investigation of the efficacy of the UV/Chlorine process for the removal of trimethoprim: Effects of operational parameters and artificial neural networks modelling

Experimental study and quantum chemical calculation of free radical reactions in ciprofloxacin degradation during the UV/chlorine oxidation process

“…According to reports, the dominant radical contributor to degradation at low pH levels was OH, while indirect radicals (Cl 2 ˙− and ˙ClO) were responsible for degradation at high pH levels. 42,43…”
