摘要: | 本研究致力於將金屬有機骨架材料製備成薄膜吸附器,並應用於水處理。選用的材料為以釤和均苯四甲酸為金屬及有機配位基之金屬有機骨架:Sm-MOF。使用非均相合成法嘗試將Sm-MOF成膜於五種不同的多孔性高分子基板上:PP膜、PVDF膜、PES膜、nylon膜及PTFE膜。接著嘗試吸附孟加拉玫紅(一種紅色染料)溶液。
我們研究發現Sm-MOF粉體對於孟加拉玫紅的飽和吸附量高達400 mg/g,與過去文獻中大多低於200 mg/g的飽和吸附量,擁有很好的表現。我們也成功使用非均相合成法將Sm-MOF長於PVDF膜、PES膜、PTFE膜及nylon膜上等多孔性高分子基板上。而長於nylon膜上之Sm-MOF薄膜吸附器對於孟加拉玫紅溶液的處理有最好的吸附效果,因Sm-MOF在nylon膜上分布地最為均勻。此外,我們的Sm-MOF相較於過去文獻中的材料,擁有非常高的薄膜透性(membrane permeance),約為4330 L/m2-bar-h。 We investigate a novel membrane adsorber comprising metal-organic frameworks (MOFs) for water treatment. A type of MOF which consists of Saranium and 1,2,4,5-Benzenetetracarboxylic acid was grown on 5 different porous polymer substrates, including PP, PVDF, PES, nylon and PTFE to form membrane by heterogeneous reaction. The membranes were applied to adsorb dye molecule, Rose Bengal, in aqueous phase. The maximum adsorption capacity for Rose Bengal of Sm-MOF powder was estimated to be about 400 mg/g, which is better than most of other materials. We also fabricated Sm-MOF successfully on various porous polymer substrates, including PVDF, PES, nylon and PTFE. The Sm-MOF membrane adsorber fabricated based on nylon was found to have the highest dynamic adsorption capacity, since it was the most uniform one. Our membrane adsorbers exhibited water permeance ( 4330 L/m2-bar-h) exceeding that of most existing membrane adsorbers. |
