摘要
借助X-射线衍射和X-射线光电子能谱分析手段，比较了几种活性碳纤维在水相中吸附前后的结构。研究结果表明，活性碳纤维吸附染料后，其微晶结构发生了变化，依吸附质的不同，活性碳纤维的晶面间距有一定的膨胀或缩小。同时，活性碳纤维在水溶液中也发生了一系列的化学变化，其表面含氧量在吸附后有所增加或减小，显示某些有机物也可使活性碳纤维发生氧化或还原。
A comparison of crystallographic features and surface chemical characteristicsof activated carbon fiber before and after adsorption in aqueous solution was made bymeans of X-ray diffraction and X-ray photoelectron spectroscopy. The results showed thatthe layer plane spacing (d002 ) of ACF changed with dye adsorption. At the same time,surface oxygen contents of ACFs were also varied after adsorption, which indicated theadsorption of organic substance would lead to the oxidation or reduction of ACFs.
