摘要 挥发性有机化合物(VOCs)由于其具有的毒性、致突变性和致癌性,严重威胁人类健康和生态环境。VOCs排放量的持续增加以及法律的严格规定,使得减少VOCs的排放更加势在必行。现今,相继出现的VOCs的处理技术有很多,诸如生物降解、焚烧、催化氧化、吸收、吸附等。其中,吸附技术由于具有特有的优点,如可回收、再利用吸附剂等,在制定控制策略时,常被看作是高效且经济的一种。碳质吸附剂由于其具大比表面积、丰富的多孔结构、吸附量高等特点,在气体净化中得到了广泛的应用,特别是在VOCs的处理和回收方面。本文列举了近年来各种碳质吸附剂对VOCs的吸附情况,以期对其进行深入研究。 Volatile organic compounds(VOCs)seriously threaten human health and ecological environment because of their toxicity,mutagenicity and carcinogenicity.With the continuous increase of VOCs emissions and strict laws,it is imperative to reduce VOCs emissions.Nowadays,there are many treatment technologies for VOCs,such as biodegradation,incineration,catalytic oxidation,absorption and adsorption.Among them,adsorption technology,because of its unique advantages,such as recovery and reuse of adsorbents,is often regarded as an efficient and economical one when formulating control strategies.Because of its large specific surface area,abundant porous structure and high adsorption capacity,carbonaceous adsorbent has been widely used in gas purification,especially in the treatment and recovery of VOCs.In this paper,the adsorption of VOCs by various carbonaceous adsorbents in recent years is listed,in order to further study it.
