中文摘要	气凝胶是一种新型纳米多孔非晶材料,其密度低、比表面积大、孔隙率高,可以作为吸附剂。本文研究了稻壳灰为硅源制成的含甲基的疏水性二氧化硅气凝胶对水中微量苯酚和甲醛的吸附性能。结果表明,疏水性气凝胶对水中微量苯酚和甲醛具有一定的吸附能力,实验中对苯酚的吸附容量是1.93mg/g,要大于对甲醛的吸附容量0.92mg/g;增大气凝胶的疏水化程度可以增加其对水中微量苯酚和甲醛的平衡吸附容量;苯酚的吸附平衡等温曲线符合Langmuir和Freundlich方程,甲醛的吸附平衡等温曲线符合Freundlich方程。; Silica aerogel,due to its properties of highly porous,low density,high surface area and nano-size pores,has potential applications in adsorption. The adsorption of trace phenol and formaldehyde in water on a hydrophobic silica aerogel was investigated. The effects of on the adsorption of the temperature,the hydrophobility of the aerogel were studied. The adsorption equilibrium characteristics were determined. The adsorption capacity for phenol is 1.93mg/g,which is higher than 0.92mg/g for formaldehyde. Increasing the hydrophobility of the aerogel could enhance the adsorption capacities for both organics. The isothermal adsorption equilibrium curves could be modeled by using Langmuir equation and Freundlich equation.; 国家自然科学基金(20576058)
