【Abstract】 Owing to the severe environmental and ecological issues arising from oil spills and toxic chemical leakage,the separation of oil from water presents a worldwide challenge to save the endangered environment.A versatile absorbent which can deal with different types of oil contaminants is in high demanded for this issue.[1-4]In this work,we obtain an ultralight,fire-resistant,and compressible foam in a large scale by directly combustion treatment using commercially available poly(melamine formaldehyde) foams as precursors.The obtained foam not only effectively separates oils from water as expected,but also possesses a very high absorption capacity for the removal of oils from water up to 145 times its own weight.More importantly,due to its fire-resistance and compressibility,distillation,combustion and squeezing,or a combination of these can be applied for recycling the foams depending on the type of pollutants,making them versatile and comprehensive absorbents to satisfy various practical separation requirements.更多还原
