【摘要】：納米纖維素是一大類(lèi)微纖單元直徑在納米級(jí)(2~100 nm)的新型纖維素材料,因其長(zhǎng)徑比高、比表面積大、力學(xué)性能優(yōu)異及表面易于化學(xué)修飾,成為現(xiàn)今生物質(zhì)吸附材料領(lǐng)域的研究熱點(diǎn)。本文總結(jié)了近年來(lái)納米纖維素基吸附材料方面的研究成果,介紹了以納晶纖維素(NCC)、納纖化纖維素(NFC)以及細(xì)菌纖維素(BC)為基材的吸附材料,及其在移除染料、重金屬、CO_2氣體和其他污染物(如抗生素、芳香族有機(jī)物、放射性元素、易揮發(fā)的有毒有機(jī)物)的研究進(jìn)展。最后,本文對(duì)納米纖維素基吸附材料存在的問(wèn)題進(jìn)行探討,并對(duì)其未來(lái)發(fā)展前景進(jìn)行了展望。
[Abstract]:Nanocellulose is a new type of cellulose material with the diameter of microfiber unit at the nanometer level (2 ~ 100 nm), because of its high aspect ratio, large specific surface area, excellent mechanical properties and easy chemical modification on the surface. It has become a research hotspot in the field of biomass adsorption materials. In this paper, the research achievements of nanocellulose based adsorption materials in recent years are summarized, and the adsorption materials based on nanocrystalline cellulose (NCC), nanofilament cellulose (NFC) and bacterial cellulose (BC) as substrate, and their removal of dyes are introduced. Advances in heavy metals, CO_2 gases and other pollutants (e.g. antibiotics, aromatic organic matter, radioactive elements, volatile toxic organic matter). Finally, the problems of nanocellulose based adsorption materials are discussed, and the prospect of their future development is prospected.
