Popis: | P-cresol formaldehyde resin was prepared and characterized by FTIR technique, then composited with polystyrene in order to produce electrospun nanofiber membrane by the electrospinning method. Zinc oxide nanoparticles was prepared and characterized by FTIR, XRD SEM and EDX techniques in order to modified first membrane. Both prepared nanofiber membranes characterized by SEM and EDX techniques and used as adsorbents to adsorb methylene blue dye from their aqueous solutions. The factors of adsorption were investigated, contact time, initial concentration, adsorbent dosage, ionic strength and temperature. The adsorption isotherms described by Langmuir and Freundlich models. So, thermodynamic functions ∆G, ∆H and ∆S of adsorption were estimated. |
