将商品化的磁性海绵浸泡在含有Fe 3 O 4磁性纳米颗粒和低表面能化合物Actyflon-G502的溶液中，在超声作用下，一步制备出具有高效油水分离能力的超疏水磁性海绵。所制备的海绵可以由磁体驱动到污染水域以选择性地从水中吸收油。所制备的海绵对不同类型的油和有机溶剂的吸油量高达其自身重量的25-87倍。此外，所制备的海绵显示出优异的可回收性，可以预测其为油水分离的理想候选物。(C)2017年爱思唯尔B。版权所有© 2016
The superhydrophobic magnetic sponge with the ability for highly-effective oil-water separation is facilely fabricated by a one-step method through dipping of commercial sponge in a solution containing Fe3O4 magnetic nanoparticles and low-surface-energy compound Actyflon-G502 under ultrasonication. The as-prepared sponge can be driven by a magnet to the polluted water zone to selectively absorb oils from water. The oil absorption capacities of the as-prepared sponge for different types of oil and organic solvents are high up to 25-87 times of its own weight. Moreover, the as-prepared sponge shows excellent recyclability, which can be forecasted as an ideal candidate for oil-water separation. (C) 2017 Elsevier B. V. All rights reserved.
