摘要/Abstract

摘要： A new type of benzene adsorption material was prepared by using the airtight heat treatment method. This method can directly transform the organic impurities of the activated alumina waste into carbon with adsorption capability. The microstructure and carbon content of materials were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), BET (Brunauer Emmett Teller) surface area analysis and elemental analysis. The influences of heat treatment temperature on the properties of the composite materials were discussed. The benzene adsorption capability of the material was investigated. The experimental results show that the optimal heat treatment process condition is airtight heating at 400℃ for 2 h. The resulting sample has carbon mass fraction of 3.57%, specific surface area of 234.70m2/g, pore volume of 0.41m3/g, and average pore size of 6.59 nm. The samples show excellent benzene adsorption capability with an adsorption rate of 21.80%.
