Adsorption properties of nickel oxide nanoparticles for removal of Congo Red from aqueous solution
The effective removal of dyes from aqueous wastewaters is among the most important issues formany industrialized countries. Removal of Congo Red (CR) dye from aqueous solutions was studiedusing nickel oxide nanoparticles. The operating variables studied were initial pH of solution,adsorbents dosage, temperature and contact time. The morphological information of nickel oxidenanoparticles were ch...

متن کاملPhotocatalytic removal of Acid Red 88 dye using zinc oxide nanoparticles fixed on glass plates
In this study, ZnO nanoparticles fixed on glass plates were employed as photocatalysts for the degradation of Acid Red 88 (AR88) dye in aquatic solution. ZnO nanoparticles were synthesized through coprecipitation method and fixed on glass plates. X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques were used for characterization of nanoparticle samples. A batch reactor equi...
متن کاملEXPERIMENTAL STUDIES ON CONGO RED ADSORPTION BY TEA WASTE IN THE PRESENCE OF SILICA AND Fe2O3 NANOPARTICLES
In this work, the adsorption of the anionic dye, Congo red (CR), from aqueous solution by using tea waste (TW) has been carried out at 30 °C. The equilibrium sorption isotherms and kinetics were investigated. The equilibrium adsorption was studied by the Langmuir and Freundlich models of adsorption. The experimental results manifested that the Langmuir isotherm was the best model for the adsorp...
متن کاملEfficient adsorption and photocatalytic degradation of Congo red onto hydrothermally synthesized NiS nanoparticles
NiS nanoparticles (NiS NPs) have been hydrothermally prepared and characterized by the methods of X-ray diffraction, scanning electronic microscope, X-ray photoelectron spectroscopy, UV-Vis diffuse reflectance spectra, photoluminescence, and thermogravimetric analysis. NiS NPs exhibit fast adsorption in the removal of Congo red (CR) in aqueous solution, in which the pseudo-second-order model wa...
