活性炭纤维的表面结构及其吸附模式
THE SURFACE STRUCTURE OF ACF AND ITS ADSORPTION MODE
-
摘要: 迄今的吸附模式,Henry定律、Langmuir模型、BET模型、D-R方程、D-A方程都分别适用于不同的表面结构,对于活性炭纤维(Activated Corbon Fiber,ACF)这种特殊的炭吸附材料适用于哪种吸附模型,未见有文献专题论述.本论文在对ACF材料进行了大量表面结构研究的基础上,对ACF的表面结构与颗粒活性炭(Granular Activated Carbon,GAC)的表面进行了对比,并尝试性地对适用于ACF的吸附模式进行了计算和比较,得到了一些有价值的结论.

Abstract: The differences between the surface structures of ACF(Activated Carbon Fiber)and GAG(Granular Activated Carbon)have been studied. Up to now, the adsorption modes, such as Henry law, Langmuir mode, BET mode, D-R, D-A equation, are respectively suitable to different surface structures. Which mode is suitable to the ACF surface is not reported in the former papers. In this paper, the calculation and choose of the mode suitable to the ACF are carried out based on the research on the surface structure of ACF. Results and explanations are given.-
