Advances in pretreatment methods for carcinogenic aromatic amines in textiles
Aiming at the problems of large amount of reagent,cumbersome process and solvent volatilization in the pretreatment process of carcinogenic aromatic amines in textiles for traditional liquid-liquid extraction and solid-phase extraction,the pretreatment methods for the detection of carcinogenic aromatic amines in textiles in recent years were comprehensively studied in this paper,including conventional liquid-liquid extraction,dispersed liquid-liquid microextraction,vortex assisted liquid-liquid microextraction,single drop liquid-liquid microextraction,aqueous two-phase extraction,solvent induced phase change microextraction,traditional solid-phase extraction,direct solid-phase microextraction,membrane added solid-phase microextraction,accelerated solvent extraction and other methods.Through comparison,it was found that liquid-liquid microextraction and membrane added solid-phase microextraction use less organic matter and have simple operation process,which is suitable for the extraction development direction of the project.However,it is necessary to increase the research on increasing the extraction head of carcinogenic aromatic amines with membrane solid-phase microextraction,and the effects of textile components and processes on the extraction process of membrane solid-phase microextraction and liquid-liquid microextraction,so as to finally establish an extraction method suitable for carcinogenic aromatic amines of textile varieties.
