TiO_2-C modified PVDF membrane for the treatment of pharmaceutical wastewater

摘要

TiO_2-C nanocrystals were synthesized by a hydrothermal method. Then modified Polyvinylidene Fluoride (PVDF) membrane was prepared through a phase inversion method by combining TiO,-C with PVDF casting solution. Pure water flux, BSA adsorption of different membranes was determined. Simulation wastewater (pharmaceutical wastewater: river =1:1) was used for treating by membranes. Three different indexes (including ammonia nitrogen, total phosphorus and COD) were determined. Results shows that when TiO,-C reached 0.5%, the modified membrane has a high application potential.
