Investigation of affecting operational parameters in photocatalytic degradation of reactive red 198 with TiO2: optimization through response surface methodology
Dye-containing wastewater generated from textile industries is a major source of environmental pollution. Azo dyes, which are the largest group of coloring agents, are widely used in industries.This research investigated the photocatalytic decolorization and degradation of an azo dye Reactive Red 198 (RR198) in aqueous solution with TiO2-P25 (Degussa) as photocatalyst in slurry form using UV li...
متن کاملPhotocatalytic degradation of mecoprop and clopyralid in aqueous suspensions of nanostructured N-doped TiO2.
The work describes a study of the oxidation power of N-doped and undoped anatase TiO(2), as well as TiO(2) Degussa P25 suspensions for photocatalytic degradation of the herbicides RS-2-(4-chloro-o-tolyloxy)propionic acid (mecoprop) and 3,6-dichloro-pyridine-2-carboxylic acid (clopyralid) using visible and UV light. Undoped nanostructured TiO(2) powder in the form of anatase was prepared by a so...
متن کاملحذف 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...
متن کاملEffect of Formation of Ag2Ti4O9 Phase on Photocatalytic Activity of Ag-TiO2 Nanocomposite
Ag-TiO2 nanocomposite with the optimum concentration of 1wt% was produced by a sol-gel process using Rhodamine B for the catalytic activity. The initial samples were prepared by heat treatment at various temperatures (266, 338, 390, 485, 600 and 700°C) with a holding time of 2 h. DTA and XRD of these samples led to choosing the temperature of 530°C as the heat treatment temperature. Then some s...
متن کاملSynthesis of nanocomposite based on Semnan natural zeolite for photocatalytic degradation of tetracycline under visible light
This study investigated the photocatalytic behaviors for the nanocomposite of TiO2 P25 and Semnan natural zeolite in the decomposition of tetracycline under visible light in an aqueous solution. The structural features of the composite were investigated by a series of complementary techniques that included X-ray diffractometer (XRD), Fourier transform infrared spectroscopy (FTIR), scanning elec...
