Sulfonamide antibiotics (SAs) are often used to treat bacterial infections of aquatic animals. Owing to the low bioavailability and degradation, residues of SAs in waters of aquaculture sites have been reported. Photocatalytic degradation with Ti02 are effective in treating residues of SAs in water. However, the efficiency of photocatalysis in water treatment of aquaculture might still be limited due to the characteristics of water quality in aquaculture system.
