Poster summary

Water is essential to life for maintaining biological processes. A small portion (0.65%) of the total water mass can be directly used by human. The remaining water mass are contaminated by using pharmaceuticals, pesticides etc., improperly. Thus, in this work, bismuth-doped titania (BixTiO2) with improved oxygen vacancies and Ti3+ was synthesized as a novel peroxymonosulfate (PMS) activator. PMS and adsorbed oxygen molecules could efficiently be transformed into their respective radicals through defect ionization. These radicals were successfully employed for the efficient removal of flumequine (FLU) contaminant, in the aquatic environment. For efficient application in real aquatic system different wastewater concern parameters were applied to get prolific results. Moreover, the as-synthesized Bi-TiO2 material was fully characterized. The kinetics, degradation pathways, ecotoxicity, and catalytic mechanism for recalcitrant FLU were also elucidated. Cost-efficient and environment-friendly recommends this design strategy; BixTiO2/HSO5- system is a promising advanced oxidation process for the aquatic environment remediation.
