【摘要】 利用模板法合成介孔纳米γ-Al2O3,用透射电镜(TEM)、X射线衍射(XRD)、比表面测定(BET)等手段对所得的介孔纳米γ-Al2O3进行了表征.考察了介孔纳米γ-Al2O3在静态条件下对硫酸根离子的吸附性能.探讨了溶液的初始浓度、pH值、时间和温度对吸附性能的影响,结果表明:介孔纳米γ-Al2O3对硫酸根离子有较好的吸附性能,其吸附行为符合Freundlich等温式.

【Abstract】 The mesoporous nanocrystal γ-Al2O3 powders were synthesized by sol-gel method and characterized by TEM,XRD,BET. The adsorption characterization of the powders to SO42- in static condition were explored. The effects of the concentration,pH,time,temperature on adsorption capacity were investigated. Mesoporous nanocrystal γ-Al2O3 has a better adsorption to SO42-. Its adsorption behavior was coincided with the equation of Freundlich.
