FeSO_4-ACF静态吸附性能的初步探讨

PRELIMINARY STUDY OF THE STATIC ADSOPTIVE PROPERTIES OF FeSO_4-ACF

探讨了经FeSO4改性处理后ACF（即FeSO4－ACF）静态吸附性能。运用TG、XRD、元素分析等手段表征了改性前后ACF结构和性能的变化。由此得到一些有趣的结论。实验证明，FeSO4改性后ACF结构发生了变化：比表面积减小，表面含氧量增多，乱层石墨碳网平面追到一定程度破坏；其吸氨量及吸苯性能均大大增强，而且已证明在FeSO4-ACF上吸苯和吸氨吸附位不重合。

The static adsorptive properties of ACF modified with FeSO4 solution have been investigated, and the difference of ACF between before and after modification was characterized by TG, XRD element analysis. The experiment found that the structure of ACF was different from the original ACF after FeSO4 modification, and during the modification, the S. S. A was decreased, the oxygen content increased, and the crystalline structure destroyed. The static adsorptive capacity of ammonia and styrene was enhanced compared with the original ACF. It was proved that the adsorption sites of ammonia was different from the styrene's.
