In this research, adsorption of dibenzothiophene (DBT) as a model of sulfur containing material has been studied by Pb exchanged Y-zeolite under different experimental conditions. The adsorption was kinetically fast and high adsorption capacity was obtained. The equilibrium adsorption data were analyzed using Langmuir and Freunlich isotherm models. The corresponding parameters and correlation c...

Phosphorus from excess fertilizers and detergents ends up washing into lakes, creeks, and rivers. This overabundance of phosphorus causes excessive aquatic plant and algae growth and depletes the dissolved oxygen supply in the water. In this study, aluminum-impregnated mesoporous adsorbents were tested for their ability to remove phosphate from water. The surface structure of the materials was ...

organic solvents. In this study, NiFe2O4/sawdust nanocomposite was synthesized for removingoil pollutants. The oil-adsorbing nanocomposite could be easily separated from water bymagnet bar. The XRD results show tetragonal phase proving the composite formation. TheFESEM pictures successfully reveal the growth of NiFe2O4 on the sawdust template. The FTIRbands at 422 cm-1 and 615 cm-1correspond to...

carbon nanotubes (cnts) are a novel material that exhibits good adsorption behavior toward various toxic pollutants in aqueous solution. these adsorbents have a fast adsorption rate and high adsorption efficiency, efficient to remove various pollutants and they are easy to recover and reuse. these features highlight the suitability of cnts for the treatment of water polluted with heavy metal io...

background: heavy metals, even at low concentrations, are harmful to human health and environment. cadmium as a heavy metal is highly toxic and can cause serious threat to living organisms. this research was designed to evaluate the adsorption potential of modified magnetic iron nanoparticles by 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol ligand for the removal of cadmium ions from water solu...

a good understanding of adsorption equilibrium and thermodynamics is required to design and operate an adsorption process. this study was conducted to assess the adsorption percentage of pb2+ ions as a function of contact time, solution ph and temperatures, and adsorbent dosage through a series of batch experiments. the methods including zeta potentials, specific surface area measurements and t...

the poly(ethyleneimine)-functionalized silica has been developed successfully as an effective adsorbent for the adsorption removal of cu(ii) ions from electroplating wastewater. the influences of ph, contact time and initial concentration of cu(ii) ions on the adsorption capacity and the effect of adsorbent dosage on the removal efficiency of cu(ii) ions from electroplating wastewater were inve...

Triphenylmethane (TPM) dye is one of the most prevalent and recalcitrant water contaminants. Magnetic reduced graphene oxide (rGO) is an efficient adsorbent for organic pollutants removal. However, the performance and adsorption kinetics of magnetic rGO towards TPM have not yet been studied. In this study, a magnetic Fe3O4@rGO nano-composite, which could be easily removed from water with a simp...
