Abstract

In this study, Graphene and magnetic Graphene-based nano-absorbents were synthesized by Hummers method and was used in order to removal of BTEX from gasoline. The structural properties of nanoabsorbents were characterized with X-ray diffraction (XRD) and Scanning electron microscope (SEM). The absorption of pollutants were measured using UV-Vis spectrophotometer. The studied variables were the absorbent concentration, the contact time, the initial concentration of Pollutants and temprauchere. Adsorption isotherms were drawn with Longmuir, Freundlich, temkin, Freundlich-Longmuir, Dubnin-Randkovich )D-R( and Redlich-Peterson )R-P( models. The maximum adsorption capacity for BTEX was determined by Graphene 56. 8 mg/g and by magnetic Graphene 69. 6 mg/g. Experimental and Statistical results was showed that magnetic Graphene has better performance than Graphene. Kinetic models, based on the assumption of the pseudo-first-order and pseudo-second-order models, were applied to examine the kinetics of the adsorption. The results showed that kinetic data followed closely to the first-second-order model.
