环境中新型阻燃剂检测技术研究进展

Research Progress of Detection Technology of Novel Flame Retardants in the Environment

新型阻燃剂(NFRs)是传统阻燃剂受到严格管控后的推广替代品,主要包括新型溴代阻燃剂(NBFRs)、新型氯代阻燃剂(NCFRs)和有机磷酸酯阻燃剂(OPFRs)等。NFRs是一类新污染物,大多属于持久性有机污染物。目前,已有多种NFRs在世界各地被检出,引起各国的普遍关注,环境中NFRs的来源及迁移转化规律也由此成为新的研究热点。通过综述环境样品中NFRs检测技术在提取、净化和仪器检测等方面的国内外研究现状,讨论了各种分析技术的特点,分析了NFRs分析过程的质量控制与质量保证问题,展望了该领域未来的发展趋势。

Novel flame retardants(NFRs)are utilized as alternatives after traditional flame retardants have been banned or strictly phased out,mainly including novel brominated flame retardants(NBFRs),novel chlorinated flame retardants(NCFRs)and organic phosphate flame retardants(OPFRs),etc.NFRs are a group of emerging pollutants,most of which belong to persistent organic pollutants(POPs).In recent years,most of NFRs have detected in environmental matrices on a global scale.The sources,migration and transformation of NFRs in the environment have become a new research hotspot.This article reviews the current research status of the extraction,purification and instrumental detection technology of NFRs in environmental samples,discusses the characteristics of each detection technology,analyses the quality control and quality assurance in NFRs analysis,and proposes future research perspectives of this field.
