摘　　要：利用浸渍法将KMnO_4负载于活性炭上,得到改性活性炭.然后将活性炭和负载KMnO_4的活性炭置于封闭的新装修房屋内,通过测定活性炭吸附前后房间内的甲醛含量,比较两者对甲醛的吸附能力.实验结果表明,用KMnO_4改性过的活性炭其吸附能力明显增强.该研究还利用比表面积及孔隙度分析仪、场发射扫描电镜、透射电镜、粉末X射线衍射仪对负载过KMnO_4的活性炭进行表征,探讨其吸附甲醛的机理.The modified activated carbon is obtained by dip-molding potassium permanganate on activa- ted carbon. Then, put samples in the main bedroom, second bedroom, study and sitting room of a closed and decorated house compare activated carbon with the modified activated carbon absorbing formaldehyde. The results show that the ability of adsorbing of modified activated carbon is stronger than activated carbon evidently. Using the specific surface area and Porosity analyzer, FE-SEM and TEM and XRD, Meanwhile, the modified activated is characterized to discuss the mechanisms of adsorbing formaldehyde.
