Adsorption of aniline on aminated chitosan/graphene oxide composite material

On the basis of aminated chitosan, graphene oxide was blended to prepare ACS/GO composite material. The composite material was characterized by SEM and X-ray diffraction, and applied to the adsorption of aniline from aqueous solution and cigarette smoke. The results showed that when ACS/GO composite material was prepared, graphene oxide was more dispersed and no agglomeration occurred, the surface area of ACS/GO was 7.460 m 2 /g. The adsorption of aniline by ACS/GO could meet both the Freundlich adsorption model and the Langmuir adsorption model in water. Meanwhile, the kinetics data of the adsorption of aniline by ACS/GO was fit better into the pseudo-second-order equation. The addition of GO could help to improve the adsorption performance of ACS on aniline in cigarette smoke.
