Abstract

The invention discloses a method for detecting phenolic antibacterial agents in textiles through the combined use of in-situ derivatization, dispersive liquid phase microextraction and gas chromatography / mass spectrometry. A technical program suitable for the simultaneous detection on five types of chlorinated phenols and o-phenylphenol in the textiles is established, a target compound is extracted by utilizing a dispersive liquid phase microextraction technology after being subjected to extraction and derivatization, and qualitative and quantitative analysis is carried out by using a gas chromatograph / mass spectrometer. The method can be applicable to the determination of the five types of chlorinated phenols and o-phenylphenol in the textiles such as clothes, fiber packing, yarns, clothing materials and household decoration products. The method is simple and rapid to operate, low in cost, environment-friendly and high in enrichment efficiency.

Description

technical field [0001] The invention belongs to the technical field of product safety and detection, and specifically relates to a method for detecting phenolic antibacterial agents in textiles by in-situ derivation-dispersion liquid phase microextraction-gas chromatography / mass spectrometry Background technique [0002] Chlorine-containing phenolic compounds (pentachlorophenol PCP, tetrachlorophenol TeCP, trichlorophenol TCP, etc.) and o-phenylphenol (OPP) are commonly used as fungicides and preservatives, and their residues in leather and textiles have attracted much attention . With the continuous deepening of research on toxicity and toxicology, relevant laws, regulations and standards have been constantly amending the residue limits in textiles. [0003] At present, the pretreatment methods for the determination of chlorophenols and o-phenylphenols at home and abroad are mainly ultra-extraction, Soxhlet extraction or accelerated solvent extraction, high performance liq...
