二癸基二甲基氯化铵危害、检测及降解技术研究进展

Progress in research on the hazards, detection and degradation technologies of didecyldimethylammonium chloride

摘要:

二癸基二甲基氯化铵(DDAC)常作为杀菌消毒剂被广泛应用于食品工业、畜牧养殖、医疗等各个领域。DDAC化学性质稳定,自然条件下难以降解,随着DDAC的大量使用,其在物体表面及环境中的残留量不断增加,对机体造成不利影响。本文重点介绍了DDAC对机体的危害,分析了色谱-串联质谱、目视检测以及生物传感器等技术在检测DDAC方面的应用,总结了DDAC的降解机理及方法,指出当前研究存在的问题并对未来的研究方向进行展望,以期为减少DDAC残留带来的危害提供参考依据。

Abstract:

Didecyldimethylammonium chloride (DDAC) is widely used as a bactericidal disinfectant in the food industry, animal husbandry, medical care, etc. DDAC is chemically stable and difficult to be degraded under natural conditions, and with the large amount of DDAC used, its residue on the surface of the object and in the environment is increasing, which has a negative impact on the organism. This paper focuses on the hazards of DDAC, analyses the application of chromatography-tandem mass spectrometry , visual inspection and biosensors in the detection of DDAC, summarizes the degradation mechanism and methods of DDAC, points out the problems of the current research, and looks forward to the direction of the future research, with a view to providing a reference basis to reduce the hazards brought by the residues of DDAC
