摘要:

针对含油废水严重污染水生态环境和影响水资源循环利用的问题,采用水热法合成十六烷基三甲基溴化铵(CTAB)改性二硫化钼(MoS2),并通过浸渍法将其负载于聚氨酯海绵表面,成功制备了一种超疏水亲油的MoS2海绵(MS海绵)。结果表明,MS海绵具有丰富的孔结构、良好的机械强度和优异的稳定性。在油水分离性能方面,MS海绵对食用油/水乳液的分离效率高达95.2%,显著优于未改性聚氨酯海绵,且对多种油品乳液均表现出优异的吸油能力,最高吸油量可达到96 g/g。此外,经20次重复使用后,MS海绵吸油量仍保持较高水平,且结构形状基本不变。MS海绵可实现连续油水分离,在模拟海洋溢油的处理中展现出良好的适用性。研究为油水分离材料的开发提供了新思路,也为溢油回收与含油废水治理提供了高效、低成本的技术方案。

Abstract:

To address the serious pollution of aquatic ecosystems and the impediment on water resource recycling caused by oily wastewater, molybdenum disulfide (MoS2) modified with hexadecyltrimethylammonium bromide (CTAB) was synthesized via a hydrothermal method and loaded onto the polyurethane sponge via an impregnation method to successfully prepare a super hydrophobic and oleophilic MoS2 sponge (MS sponge). MS sponge exhibited a rich porous structure, good mechanical strength and excellent stability. The separation efficiency of MS sponge for edible oil/water emulsion was 95.2%, significantly outperforming the unmodified polyurethane sponge. It showed excellent oil absorption capacity for various oils, with the maximum reaching up to 96 g/g. Moreover, the oil absorption capacity of MS sponge remained high even after 20 cycles of reuse, and the shape also remained basically unchanged. Meanwhile, MS sponge could achieve continuous oil-water separation and demonstrated good applicability in the treatment of marine oil spills. This study provides new ideas for the development of oil-water separation materials and also provides an efficient and low-cost technical solution for the practical application of oil spill recovery and oily wastewater treatment.
