[ 1 ] - Adsorptive desulfurization of oil derivatives using nanostructured Mg-Al layered double hydroxides: Experimental design and modeling
This study focuses on the application of nanostructured Mg-Al layered double hydroxide as a promising adsorbent in desulfurization of dibenzothiophene, an aromatic sulfur bearing compound from gasoil model. The Mg-Al LDH was synthesized by a co-precipitation method and characterized by FT-IR, XRD, EDX and SEM. The XRD and FT-IR approved the layered structure and crystalline form of the adsorben...
[ 2 ] - 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...
