采用简单方法一步合成吡啶基团功能化的介孔材料,并研究其对2,4,6-三硝基苯酚和银离子的吸附性能。考察了p H、吸附时间、初始浓度等因素对吸附性能的影响。实验结果表明,所合成的材料对2,4,6-三硝基苯酚的吸附量达到515.46 mg?g-1,对银离子的吸附量达到12.45 mg?g-1。

Pyridine-functionalized mesoporous materials were synthesized via simple one-pot condensation. The adsorption properties of the material for 2,4,6-trinitrophenol and Ag＋ were studied. Several influencing factors were investigated to find the best adsorption condition, such as p H, contacting time and concentration. Experimental results show that the maximum adsorption capacity of synthesized material is 515.46 mg·g^-1 for 2,4,6-trinitrophenol and 12.45 mg·g^-1 for Ag^＋.
