摘　　要：本文制备了一种特殊浸润性油水分离海绵(PVMS-SM),具体考察所制备材料的疏水、亲油等浸润性能及在油水混合物中的选择性。利用该材料的超疏水亲油性,建立了PVMS-SM海绵结合液液提取法检验水中微量油类助燃剂的新方法,该方法操作简便快速,灵敏度高,可用于实际案件中油类助燃剂的检验。A oil-water separation sponge(PVMS-SM)with special wettability behavior was prepared,and the wettability properties such as hydrophobicity,lipophilicity and the selectivity in oil-water mixtures of this material were specifically investigated.Utilizing the super-hydrophobicity and lipophilicity of the material,a new method was established for the detection of trace petroleum-based accelerants in water by the PVMS-SM sponge combined with the liquid-liquid extraction.The method is simple,rapid and sensitive,and can be used for the detection of petroleum-based accelerants in practical cases.
