摘要:Removal of oil and organic pollutants from water is desired due to the frequent oil spill accidents and increase of industrial oily wastewater. The development of absorbent materials with high absorption capacity for separation and removal of oils from water should be of great importance to address environmental issues. In this paper, we reported a simple method to hydrophobic surface modification, which fabricated by palmitic acid solution-immersion processes, as well as their excellent adsorption performance for oils and organic solvents. The hydrophobicity, oil-absorption capacity and selectivity of the as-prepared sponges were evaluated. The results show that the sponges fast and selectively absorbed various kinds of oils up to above 33 times their weight. These sponges have great potentials for large-scale removal of oil or organic solvents spills from water.
