摘要:
为解决印染废水处理中吸附材料去除能力不足及回收困难的问题 ,开发了一种高效、可回收的吸附材料用于印染废水处理 。 以羧化壳聚糖(Carboxymethylchitosan, CMCS)为基体 ,采用溶胶-凝胶法与冷冻干燥技术 ,构建羧化壳聚糖/硅烷气凝胶(CSAP) ,并利用原位生长法将铜基金属有机框架(Cu-based MOFs,HKUST-1) 负载于气凝胶上 ,成功制备了 HKUST-1@CSAP复合气凝胶吸附剂 , 并对其形貌、结构与热稳定性进行表征 ; 以刚果红(Congo red,CR)为模型污染物 ,分析 HKUST-1@CSAP复合气凝胶对 CR的吸附行为 ,探讨其吸附作用机理 。结果表明 :HKUST-1成功负载于 CSAP气凝胶骨架中 ,所得 HKUST-1@CSAP复合气凝胶具有高比表面积以及良好的热稳定性和力学稳定性 。在染料初始质量浓度 800 mg/L、pH 值 10~ 12、40 ℃、吸附剂用 量 15 mg 的条件下 , HKUST-1@CSAP复合气凝胶对刚果红的实际最大吸附量可达 1107.27mg/g,吸附过程符合准二级动力学模型和Langmuir等温模型;经过 5 次吸附-脱附循环后 ,材料仍能保持 82%以上的吸附容量 ,表现出良好的再生性能与结构稳定性 。该研究制备的 HKUST-1@CSAP复合气凝胶兼具高比表面积、优异的吸附性能和良好的循环使用潜力 ,可为多糖基 MOF复合材料在污水处理中的应用提供新思路。
