Abstract

To recover dyes and reuse adsorbents in the process of dye wastewater treatment, a new composite adsorbent based on viscose fiber cloth and Cu–BTEC MOFs was designed. The MOF materials were evenly distributed on the fiber surface via an in situ hot pressing process. The adsorbent could effectively adsorb methylene blue as the model dye in the solution, and the adsorption efficiency could reach 84% in 4 h. When the adsorbent is spent after several adsorption cycles, it could be recovered to a higher adsorption efficiency by UV catalytic regeneration. Hence, the explored material should be applicable in the field of wastewater treatment.

基于粘胶纤维布/ Cu-BTEC MOFs的紫外线辐射再生吸附剂对亚甲基蓝的吸附

摘要

为了在染料废水处理过程中回收染料并再利用吸附剂，设计了一种基于粘胶纤维布和Cu-BTEC MOF的新型复合吸附剂。通过原位热压工艺将MOF材料均匀地分布在纤维表面上。该吸附剂可以有效地吸附作为模型染料的亚甲基蓝溶液，吸附效率在4 h内达到84％。当吸附剂在几个吸附循环后用完时，可通过UV催化再生将其回收到更高的吸附效率。因此，所研究的材料应适用于废水处理领域。
