摘要：NOx是文物保存环境的一类重要的污染物,近期采用资源丰富、价格便宜的竹材及竹炭作为吸附剂去除污染物成为热点。本工作采用低温竹炭净化低氮氧化物,并对效果的影响因素进行了探讨,使用扫描电镜对低温竹炭表面形态进行了研究。研究表明,低温竹炭处理浓度在133～457μg/m^3NO时,处理效率可以达到84%～94%,处理浓度在82～453μg/m^3NO_2时,处理效率可以达到93.3%～97.7%。当NO和NO_2同时存在时,NOx在500μg/m^3时(NO:NO_2=2:1),NO的处理效果下降,仅能达到44.7%,但是NO_2的处理效果变化不大,仍可以达到98%。
NOx is an important kind of pollutants relevant for cultural relic conservation.It has been noted recently that bamboo carbon is a plentiful and cheap adsorbent for removing pollutants.In this paper,the adsorption effect of low - temperature bamboo carbon for removing NOx is studied.Surface modification of low - temperature bamboo carbon was studied by SEM.Results of these studies showed that low - temperature bamboo carbon can remove between 84%～94%of NO when initial concentration of NO is between 133~457μg/m^3 and is between 93.3%~ 97.7%of NO_2 when concentration of NO_2 is between 82~45μg/m^3.When NOx,which is a mixture of NO and NO_2,is 500μg/m^3,the adsorption level for NO decreases to 44.7%,whereas it remains at 98%for NO_2.
