摘要

Abstract

AC-NaOH/GO composite adsorption material was prepared by modifying activated carbon(AC)with NaOH and graphene oxide(GO)step by step.The microstructure and adsorption properties of AC-NAOH/GO and its benzene adsorption performance were analyzed by SEM and FTIR.The experimental results show that NaOH-modified AC has more abundant micropore structures,which is conducive to improving the adsorption capacity,and adding a small amount of GO can improve the adsorption selectivity of benzene vapor.When the mass ratio of AC-NaOH to GO is 1∶0.1,compared with AC,the specific surface area and total pore volume of AC-NaOH/GO-1 are increased by 46.3%and 16.8%,respectively,and the adsorption equilibrium amount and adsorption equilibrium time of benzene vapor are increased by 56.1%and 14.77%,respectively.After vacuum heat treatment,the π-π electron diffusion between GO and AC-NaOH is enhanced,which is conducive to increasing the benzene adsorption capacity.
