In this paper, the adsorption technique was employed to remove crystal violet (CV) dye from aqueous solutions and usage as adsorbent material for a composite graphene oxide/polyvinyl pyrrolidone/acrylamide (P(PVP-co-AAm)/GO) that prepared by hummer modified method .the composite was illustrated via different analysis apparatus included FTIR, TGA and FE-SEM. In batch optimization studies, were conducted to determine the optimum conditions for adsorption for each of the following factors (acidic function, temperature, ionic strength, Weight of graphene oxide, equilibrium time). The thermodynamic functions were calculated for the adsorption process, and it appeared the reaction was endothermic, non-regular, and spontaneously. Empirical data have been modeled using first and second-order. The adsorption data were fitted with Freundlich and Timken isotherms. [ABSTRACT FROM AUTHOR] |
