- Abstract:
- As antibiotic contamination in aquatic environments intensifies, it becomes crucial to develop efficient and stable technologies for antibiotic removal. The sono-photocatalytic membrane reactor (SPMR) was investigated to use Bi2MoO6/FeVO4 core-shell nanomaterials as catalysts and ultrafiltration membranes for separation, focusing on its effectiveness in removing ciprofloxacin (CIP) from water. The degradation rate of CIP in the SPMR increased with hydraulic retention time (HRT) and reached 94.56% when HRT was 60 min. The hollow fiber membrane effectively retained the catalyst, ensuring stable catalyst concentration within the reactor. Hydroxyl radicals (·OH) and holes (h+) played a key role in the degradation process. The SPMR exhibited excellent removal efficiency for CIP across various real and synthetic water sources, with degradation rates consistently above 80%. This research confirms the feasibility of sono-photocatalytic technology for CIP removal in different water bodies.
