海上溢油问题及含油废水的排放对经济与环境带来了巨大的破坏。在处理这些问题的方法中,吸附法被认为是一种最为经济、高效和环保的方法。改性吸油海绵由于成本低、孔隙率高、设计灵活及三维骨架结构使其在油水混合物处理领域备受关注。然而,普通海绵由于其亲水-亲油性限制了油水处理中的应用。总结了为解决海绵此类问题而赋予海绵选择吸附性能及提高其吸附性的改性方法。
Marine oil spills and emissions of oily wastewater have caused enormous damage to the economy and the environment.Among the methods for dealing with these problems,the adsorption method is considered to be the most economical,efficient and environmentally friendly method.The modified oil-absorbing sponge has attracted much attention in the field of oil-water mixture treatment due to its low cost,high porosity,flexible design and three-dimensional skeleton structure.However,ordinary sponges limit their use in oil water treatment due to their hydrophilic-lipophilic nature.The modification methods that given the sponge selective adsorption performance and improved its adsorption to solve such problems of sponge were summarized.
