Photocatalytic degradation of rhodamine B by nano bismuth oxide: Process modeling by response surface methodology (RSM)
The photocatalytic activity of nano-Bi2O3 was evaluated in degradation of rhodamine B (RhB) as a model of dye pollutant from waste waters. Nano sized Bi2O3 was synthesized using the chemical precipitation method. The as-prepared sample was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared spect...
متن کاملFabrication Fe3O4/SiO2/TiO2 Nanocomposites and Degradation of Rhodamine B Dyes under UV Light Irradiation
Recycling and reusing of catalyst is an important factor to produce capable and low cast catalysts. Silica coated magnetic nanoparticles (Fe3O4/SiO2) were synthesized via a simple sol-gel method with the aid of sonication. Fe3O4 nanoparticles. After that a layer of TiO2 was constricted by hydrolyze and condensation of Teteranormalbuthyltitanate to produce Fe3O4/SiO2/TiO2 nanocompsite. As-synthe...
متن کاملEffect of WO3 Nanoparticles on Congo Red and Rhodamine B Photo Degradation
Tungsten trioxide nanoparticles with two different sizes (average particle sizes about 50 and 80 nm) were prepared by the spray pyrolysis method. Photo degradation of Congo Red (azo dye) showed that photo catalytic property of the as-prepared WO3 nanoparticles with average size about 80 nm is higher than the sample with average size about 50 nm. Photo degradation of Rhodamine B (...

متن کاملEffects of Ultrasound Working Parameters on the Ultrasonic Power Density Some Neglected Problems in the Application of Ultrasound Bath
Ultrasound has been widely employed in food industry, while some of its working parameters are usually neglected to be described in its application, which caused the difficulty of reproducing and comparing the results obtained by different groups. So it is definitely not sufficient to simply state the ultrasound conditions such as ultrasound power, frequency and t...
