多环芳烃(PAHs)是一类广泛存在于环境中的持久性有机污染物,具有毒性大、难降解的特点.综述了生物质吸附去除水环境中PAHs的国内外研究现状,着重介绍了常用生物质吸附剂如菌类、藻类、淀粉类、纤维素类和木质素类生物质及其燃烧产生的生物质炭在吸附去除水环境中PAHs的研究进展.对生物质吸附材料的选择、吸附过程的影响因素等进行了分析,并展望了生物质吸附PAHs可能的发展方向.
Polycyclic aromatic hydrocarbons(PAHs)are one kind of persistent organic pollutants which can be widely found in the environment,which has the characteristics of being toxic and difficult for degradation.The research status of the adsorption of biomass to remove PAHs in the water environment at home and abroad was reviewed.The research progress of the adsorption of PAHs biomass species,including fungi,algae,starch,cellulose and lignin biomass was introduced in greater detail.Furthermore,the selection of suitable biomass materials as adsorbents and the factors affecting the adsorption of biomass were analyzed.Finally,the prospects of the possible development trend of the biomass adsorbed PAHs were presented.
