主 题：Ozonation Ibuprofen Photo-catalyst GC-MS BOD SrWO4/ZnO
摘 要：The study was performed for removing ibuprofen from water using ozonation with visible light SrWO4/ZnO *** the removal of Ibuprofen,the overall reaction was carried out in a glass reactor in the presence of UV light and constant supply of *** maximum removal efficiency of Ibuprofen was 93%at 0.1 mg/L initial Ibuprofen concentration,and 0.35 g/L catalyst concentration keeping the contact time 30 *** a certain value,an increase in a concentration of doping agent,catalyst as well as initial Ibuprofen concentration results in a decrease of efficiency of the *** prepared photo catalysts were characterized by X-ray diffraction,FTIR spectra and SEM *** peaks and FTIR spectra has clearly shown that the doping of SrWO4 with ZnO showed better result as compared to *** analysis showed that they spherical nano-composite crystals were dominant in *** character was found to reduce after ozonation of *** by products were formed and were identified through GC-MS *** results,it was found that combination of SrWO4/ZnO was able to remove 93%of ibuprofen and 0.4%dopping of ZnO on SrWO4 was found to be *** pattern of by products were identitified in GC-MS with various mass ratios as 177,92,57,*** 55%removal of BOD was observed in this *** study was found to be useful for removal of pharmaceuticals and other similar pollutants from water effectively.
