环境中偏二甲肼检测方法的研究进展

Research progress on detection methods of 1,1-dimethylhydrazine in environment

目的近年来,由于偏二甲肼在航天工业的广泛使用,偏二甲肼对人体健康的影响不可忽视。因此,如何准确高效的检测环境中偏二甲肼的残留已成为人们研究的热点,但偏二甲肼强还原性、易燃易爆,检测也较难。本文综述了近年来对环境中偏二甲肼检测方法的研究,详细介绍了液相色谱法、气相色谱法、质谱法、传感器法等不同检测方法的异同点,同时总结了不同方法的检出限、线性范围和回收率。

In recent years,due to the wide use of 1,1-dimethylhydrazine(UDMH)in the aerospace industry,the its impact on human health cannot be ignored.Therefore,how to detect UDMH in the environment accurately and efficiently become a research hotspot.However,it is difficult to detect UDMH because of its strong reducibility and inflammability.The article reviews the research on the detection of UDMH in the environment in recent years,introduces the similarities and differences of different detection methods such as liquid chromatography,gas chromatography,mass spectrometry,and sensor method,as well as summarizes the limits of detection,linear range,and recoveries of different methods.
