摘要
重金属离子广泛存在于制革、印染、电镀等行业排放的废水中,这些离子大多具有毒性和致癌性,且不可被生物降解而易在环境和生物体中大量积聚。纳米纤维素具有可降解、可再生、高比表面积、高孔隙率、高吸水性和高反应活性等特性,近年来成为吸附材料领域的研究热点。综合介绍了纳米纤维素吸附材料的制备及其在重金属离子吸附方面的应用研究进展。
Heavy metal ions were widely existed in waste water of leather tanning, dying and electroplating industries, which could accumulate in living organisms and had toxicity and carcinogenicity. Nano-cellulose was an excellent adsorbent material because of the high specific surface and porous structure, high water holding capacity, biodegradability, renewability, high reaction activity. The development in the preparation and application of nano-cellulose heavy metal ions absorbent materials were introduced.
