|
摘要
采用吸附材料进行油水分离是经济且非常有效的方法。吸附材料主要有无机材料、合成高分子材料和天然有机纤维材料等。相比较而言,天然有机纤维材料为可再生生物质资源,来源广泛、生物降解性好,可有效防止二次污染,具有良好的发展潜力,备受关注。本文首先简要介绍了油水乳液稳定性的影响因素,然后综述了油水分离材料的分离原理、构建方法和分离性能等研究进展,并总结了油水乳液分离材料的表征及其分离性能的评价指标。特别地,重点总结了天然有机纤维基吸附材料分离油水乳液的研究进展。最后指出研究智能响应型天然有机纤维基油水乳液分离吸附材料是重要的发展方向。
The use of adsorption materials for oil-water separation is an economic and very effective method. The sorbents mainly include inorganic materials, synthetic polymers, natural organic fiber materials, and so on. Among them, natural organic fiber materials are renewable biomass resources and have extensive sources and good biodegradability, which can effectively prevent secondary pollution, and thus have received considerable attention recently. The factors influencing the stability of oil-water emulsions are briefly introduced. Then, we summarize the research progress on the separation mechanism,fabrication method and separation performance of the materials for oil-water separation. Meanwhile,characterization methods of the sorbents for emulsion separation and evaluation indicators of their separation performance are also summarized. In particular, we focus on the research progresses of natural organic fiber-based sorbents for separating oil-water emulsions. Finally, it is indicated that investigating the sorbents based on smart responsive natural organic fiber for oil-water emulsion separation is an important development direction.
