吸附剂纳米Fe3O4在染料废水处理中研究进展

Research Progress of Adsorbent of Nano Fe3O4 in Dye Wastewater Treatment

磁性吸附剂纳米Fe3O4不仅可以对染料废水进行快速吸附脱色,而且也能在外磁场作用下快速的从染料废水分离出来。纳米Fe3O4是近年来人们关注的应用于染料废水的新型吸附材料,本文就近些年来染料废水处理现状、吸附剂纳米Fe3O4在染料废水中应用、吸附剂纳米Fe3O4的脱附及再生的研究进展进行了综述,分析存在的问题,提出了未来研究工作的建议。

As magnetic adsorbent, Fe3O4 could not only achieve fast effective decolorization, and also could be separated from dye wastewater under the operation of the magnetic field. Nano Fe3O4 is a new adsorbent used in dye wastewater, which have attracted increasing attention recently. This paper reviews the advances in the research and development of status of dye wastewater treatment, adsorbent of nano Fe3O4 in dye wastewater treatment, desorption and regeneration of nano Fe3O4 adsorbent during the last decade. The existing problems are analyzed and suggestions for future research works are also put forward.
