現今的環境污染,不僅導致生態失衡,同時也威脅了人類的永續發展。如何解決環境污染,已成為全球所共同關切的課題。油/水分離於環境保護為非常重要的一環,可實際應用於解決工業含油污水和原油洩漏等問題。 本實驗將美耐皿海綿作為過濾膜,藉由壓縮使海綿結構更為密實,並以鹽酸鹽化增加海綿的親水特性,便可大幅提升油/水分離效果。於油/水混合液分離中,美耐皿海綿可進行連續72小時分離,分離期間流速並無明顯變動且分離後水中油含量極低,分離效果佳。於未添加乳化劑之油/水乳化液分離中,以美耐皿海綿進行分離,分離後水中油含量明顯下降,有良好的分離效果。於添加乳化劑之油/水乳化液分離中,以美耐皿海綿進行分離,分離後水中油排除率皆高達99%以上。
Oil/water separation has recently become a worldwide challenge because of the greater potential for accidental oil spills due to the growth of oil production and transportation. As a result, there is a need to develop new materials for the separation of large amounts of organic pollutants in water system. In this work, we describe simple methods for fabricating superhydrophilic and under water superoleophobic melamine sponges. Under the drive of gravity, the superhydrophilic and under water superoleophobic melamine sponge separate a range of oil/water mixtures effectively with high water flux (>40000 L/m2 ⋅ h) and good oil/water separation efficiency. The superhydrophilic and under water superoleophobic melamine sponge could also separates both surfactant-free and surfactant-stabilized oil-in-water emulsions with high separation efficiency (>99%), making it a promising candidate material for use in oil/water separations.
