摘　　要：基于缬氨酸和亮氨酸设计合成了一系列二肽相选择凝胶剂,凝胶性能测试结果表明,在室温下,负载量为5%时,Fmoc-V-V-12和Fmoc-L-L-12均能以粉末的形式在1 min内将苯、甲苯、二甲苯和汽油从油水两相体系中快速固化,然后通过简单的过滤即可实现油和水的分离。使用该凝胶剂除油具有操作简单、高效、安全、便捷等优点,有望为污水净化领域提供除污新策略。A series of dipeptide phase-selective gelators were synthesized based on valine and leucine.The gelling ability test results showed that Fmoc-V-V-12 and Fmoc-L-L-12 bothare able to quickly phase-selectively gel benzene,toluene and xylenes in the presence of water within 1 minute at room temperature at gelator loading of 5% and then separate oil and water through simple filtration.The use of the gel to remove oil has the advantages of simple operation,high efficiency,safety and convenience,and is expected to provide a new decontamination strategy for the field of sewage purification.
