摘　　要：化学嫁接法或物理浸渍法季胺基改性生物质材料结合了化学吸附与物理吸附的优点,是一种潜在的硝酸盐氮(NO3-N)吸附剂。主要论述了生物质季胺基化学嫁接改性方法,对比了两种季胺基改性生物质材料在对NO3-N的捕获效果及吸附原理,对未来去除硝酸盐新材料的研究方向进行了展望。Quaternary amine modified biomass materials by chemical grafting or physical impregnation method combine the advantages of chemical adsorption and physical adsorption,which is a potential nitrate nitrogen(NO3-N)adsorbent.This paper mainly discusses the chemical grafting modification method of biomass quaternary amine,compares the capture effect and adsorption principle of two kinds of biomass materials modified by quaternary amine on NO3-N,and prospects the research direction of new materials for nitrate removal in the future.
