Photodegradation of Antibiotic Drugs by BiVO4 Nanocomposites

BiVO4 and its composites were prepared compared with tetracycline hydrochloride, chlortetracycline hydrochloride hygromycin to simulate the target degradation species for photocatalytic experiments. All samples found have strong effects on three antibiotics, composite photocatalysts GB, PB PGB showed faster reaction rates higher activity than pure BiVO4. In addition, of each sample antibiotic solution was in accordance primary kinetic equation. The UV detection antibiotics also carried out, results that catalyst has a oxidation ability degrade small molecules.
