摘要本文遵循炭气凝胶的制备思路,先用1-丙醇苯酚和甲醛的混合物与磷酸反应,然后加入糠醛反应生成凝胶。然后在常压下进行干燥,在氮气作为保护气体进行热裂解生成单片孔的炭气凝胶,运用N2吸附/脱附、压汞测试、扫描电子显微镜测试(SEM)等表征测试手段对气凝胶进行了表征,观察了炭气凝胶的晶体结构、形貌和微观结构。并且初步探索了炭化气凝胶作为电吸附脱附氟离子中电极材料时,炭气凝胶的吸脱附氟离子性能。
试验将采用铝炭气凝胶作为电极,参考其他实验中电极材料的实验方法,将铝炭气凝胶研磨压片,制成正极材料,放入预先配置的氟离子水中进行电吸附实验。运用PH/离子浓度测试仪测量水中氟离子浓度的变化。吸附氟离子后再将其进行脱附实验,考察其脱附率是否可二次利用。由于实验时间仓促,将运用铝炭气凝胶的数据对炭气凝胶吸附脱附氟离子性能进行初步估计与展望。16000

ABSTRACT
Mixtures of phenol and m-cresol in 1-propanol were first reacted with phosphoric acid and then with furfural to form gels, which were dried under ambient pressure and pyrolyzed under nitrogen atmosphere to form monolithic macroporous carbon aerogels. and crystalline nature feature and microstructure were investigated by nitrogen adsorption ,Fourier transform infrared spectroscopy, thermo gravimetric analysis, scanning electron microscope and .And the properties of adsorption/ desorption when the carbon aerogels were used as the electrode material in electroadsorption process were simply studied.
This experiment used the carbon aerogel as the electrode material,rely on the other test method of the electrode material,first grind the carbon aerogels ,then make it into some round-small tablets as the electrode material ,then put it into the water which is mix with fixed concentrations of the fluorine ion ,then take the Electrosorption experiment .Use the PH/ion concentration tester to measure the change of the concentration of the fluorine ion in the water .Then take out the carbon aerogel which make as the electrode material to take the Electrodesorption experiment to inspect the desorption rate of the carbon aerogel ,then according to the desorption rate to analyse if the carbon aerogel which used as the electrode material can be used as the renewable resource .For the lack of the time, just estimated the performance of the carbon aerogel in the field of the Electrosorption and Electrodesorption. 本文来源:http://www.mamitama.com/a/www.kjrs365.com/
