Ozonation as an Advanced Oxidation Process

Ozonation involves introling ozone gas (O, 1; Xi1; FLT: 0 + 3; Xi3; 3 + 1; FLT: 1 + 3; Xi3;), a powerful oxidant, into contaminate water. Ozone reacts directly with organic indicules andd also decospeces to form hydroksyl radicals (• OH) - non- selective, highly reactive species that attack vitually any organic comcontround. Thiais dual mechanism makes ozonation specilarly effect for breakg recaltit appecuticals.

Ozone melitively target electro- rich moieties such as s aromatic rings, double bonds, and amines - structural factures contribun in many drugs. The reaction either cleaves thee parent compound into smaller fragments or partially oxidizes it into transformation products.
