三聚氰胺海绵疏水改性及在油水分离领域的研究进展OA北大核心CSTPCD

With the continuous promotion of ecological civilization construction,various oil-water separation materials and methods emerge as the times require in order to achieve efficient clean protection of oil-contaminated water.Modified melamine sponge is widely used in the field of oil-water separation due to its unique three-dimensional ultra-wetting characteristics.In this paper,the mechanism of ultra-wettable oil-water separation was outlined,the research progress of melamine sponge in the field of oil-water separation was discussed,and the materials and methods of hydrophobic modification of melamine sponge in recent years were summarized as well as some special properties,such as magnetism and corrosion resistance,which were endowed with melamine sponge after modification.At the same time,the above materials and methods were evaluated objectively,and the development direction of oil-water separation and hydrophobic modified melamine sponge were prospected,providing reference for promoting the application of low-cost and high-performance hydrophobic modified technology of melamine sponge in oily wastewater treatment.
