PFOS/PFOA替代品研究现状

Research Status of Alternatives for PFOS/PFOA

全氟(多氟)化合物(PFASs)由于其良好的热稳定性、化学稳定性、表面活性等,被广泛用于食品袋、防水衣物、灭火剂等产品中。该类物质中的典型物质为全氟辛基磺酸(PFOS)和全氟辛酸(PFOA),这两种物质由于具有疏水性、环境持久性、生物蓄积性和多种毒性,目前已列入《斯德哥尔摩公约》名单附件B中加以限制。为此,本文综述了此类物质的多种替代品研究现状。

Perfluorinated(polyfluorinated)compounds(PFASs)are widely used in food bags,waterproof clothing,fire extinguishing agents and other products due to their good thermal stability,chemical stability,surface activity,etc.Typical substances in this category are perfluorooctane sulfonic acid(PFOS)and perfluorooctanoic acid(PFOA),which are listed in Annex B of the Stockholm Convention for restriction due to their hydrophobicity,environmental persistence,bioaccumulation and multiple toxicities.To this end,this paper reviews the research status of various alternatives to such substances.
