    Synthesis of Three-Dimensional Porous Elastomer Adsorbent and Its Properties of Highly Efficient Dyes Removal

    • 摘要: 通过使用乙烯-醋酸乙烯酯共聚物将多孔炭黏附在聚氨酯泡沫骨架中,构建了一种新型三维多孔弹性体吸附剂(3D-PE)。利用扫描电子显微镜(SEM)、气体吸附分析仪、电子万能试验机、紫外-可见分光光度计等对3D-PE的结构、性质及染料吸附性能进行了表征。结果表明: 3D-PE在压缩条件下表现出高强度、优异的回弹性和良好的柔韧性,对有机染料分子具有较高的吸附速率(5 min内去除率为96%)和稳定的循环使用性。

       

      Abstract: Developing an efficient adsorbent is of great importance for wastewater treatment. Despite many examples for their synthesis exist, it still remains a challenge to fabricate a versatile adsorbent to overcome the defects of their common forms (e.g., powder, pellet, bead and flake). Herein, a novel three-dimensional porous elastic adsorbent (3D-PE) was constructed by adhering porous carbon to polyurethane foam framework using ethylene-vinyl acetate copolymer. 3D-PE was characterized by scanning electron microscope (SEM), gas adsorption analyzer, electronic universal testing machine and UV-Vis spectrophotometer. Benefitting from the rational integration of the porous carbon, ethylene-vinyl acetate copolymer and polyurethane foam, 3D-PE exhibited high strength, excellent resilience and remarkable flexibility even under compression conditions. Inspired by these impressive characteristics, 3D-PE was potentially used as an adsorbent for wastewater purification, especially in a feasible application to be operated under harsh conditions. As a proof of concept, when the adsorbents were used towards methylene blue removal, 3D-PE exhibited high adsorption rate (96% removal efficiency within 5 min), stable recyclability even under a repeatedly compressed condition. In addition, kinetics and isotherm models were fitted. It was confirmed that the adsorption of methylene blue by 3D-PE was chemisorption and multi-molecular layer adsorption. 3D-PE may hold good promising applications in wastewater remediation, catalytic reactions, and environmental engineering.
