حذف فوتوکاتالیستی آنتی بیوتیک مترونیدازول، با استفاده از نانوکاتالیست مغناطیسی TiO2 (Fe3O4@SiO2@TiO2) : سنتز، تعیین مشخصات، و پارامتر های بهره برداری

Background and purpose: Photocatalysis process with TiO2 is a well-known method for removal of pollutants from water. However, the small particle size of TiO2, and therefore difficulty in its separation after treatment impede its commercialization. The aim of this study was to synthetize the Fe3O4@SiO2@TiO2 magnetic nanoparticles (NPs) and evaluation of its efficiency in removal of metronidazol...

Contributing factors on the removal of Azo-dyes from industrial wastewater: A comparison of the efficiency of sonocataysis and photocatalysis process

The influence of the number of operating parameters on photocatalytic and sonocatalytic Acid Red 88 degradation from an aqueous solution was investigated in this paper. The experimental results indicated that the sonocatalytic process with Ni-TiO2 was far more effective for the degradation of high concentration azo dyes, regardless of the process condition. In order to achieve a larger surface ...

Photodegradation of Alachlor Over Fe - TiO 2 on Granular Activated Carbon Support under UV and Visible Light

Fe-TiO2 on granular activated carbon support was synthesized via hydrothermal method without calcination. The crystalline phases were identified using X-ray diffraction whereas the surface morphologies were examined using scanning electron microscopy. Peaks of anatase TiO2 and graphite were present in the Fe-TiO2-GAC sample. Comparisons of the surface features of GAC and Fe-TiO2-GAC show that F...

Enhanced Biohydrogen Production by Accelerating the Hydrolysis of Macromolecular Components of Waste Activated Sludge Using TiO2 Photocatalysis as a Pretreatment

The effects of TiO2 photocatalysis on the hydrolysis of protein of waste activated sludge (WAS) and its biodegradability were investigated in this study. After 12-h UV irradiation, the removal ratio of protein by TiO2 photocatalysis reached 98.1%. The optimal condition for photocatalytic degradation of protein is TiO2 dosage of 5.0 mg·L under 2.4 w·m UV light irradiation. TiO2 photocatalysis in...
