纳米纤维素吸附剂在废水处理中的研究进展

Research progress of nanocellulose adsorbent in wastewater treatment

主要以吸收废水中的染料和重金属类污染物为例,综述了纳米纤维素在废水处理方面的应用,以及国内外对于纳米纤维素吸附剂在废水处理中的研究进展。对纳米纤维素类吸附剂应用于废水处理的发展趋势进行展望,指出纳米纤维素类吸附剂研究不够深入广泛,未来还需进一步对纳米纤维素类吸附剂做更深层次的研究。新型吸附剂的发展趋势必然会向绿色环保、价格低廉、原料易得、高效并且再生性能好的方向发展。

The progress of social life is always accompanied by the environmental pollution,water pollution is the top priority of environmental governance,while the adsorption method is an efficient and economic way to solve the problem of water pollution.As a kind of bio environmental protection material,nanocellulose has excellent performance in waste water treatment due to its structure,property and universality.The application of nanocellulose adsorbent in waste water treatment is briefly described,taking adsorbed dyes and heavy metals as examples.
