Problems solved by technology

[0004] At present, the detection of polybrominated biphenyls and polybrominated diphenyl ether flame retardants in textiles at home and abroad is mainly focused on gas chromatography-mass spectrometry, and there is no detection standard for liquid phase detection of polybrominated biphenyls and polybrominated diphenyl ether flame retardants (PBBs and PBDEs) in textiles. , and there are relatively few relevant literatures in this area, and there are few institutions conducting research. If an accurate ultra-high performance liquid phase detection method for PBBs and PBDEs content in textiles can be found, it will fill the gap in the detection of PBBs and PBDEs in textiles in China. Provide scientific raw data for formulating relevant method standards

Embodiment Construction

[0023] Below in conjunction with accompanying drawing, the present invention will be further described

[0024] Take the self-made heptabromobiphenyl (PBB7) positive textile sample, cut it into small pieces with a size not exceeding 5mm×5mm, mix well, weigh 1.00g (accurate to 0.01g) of the textile sample, and place it in 50mL Add 20mL of n-hexane-acetone (7+3) to the Erlenmeyer flask with a stopper, extract in an ultrasonic generator for 20min, filter the extract, and extract the residue with 5mL of n-hexane-acetone (7+3) for 20min, and combine The filtrate was collected in a 100mL concentrator bottle, concentrated to near dryness in a water bath rotary evaporator at 40°C, and fixed to 2.0mL with n-hexane-acetone (7+3) solution, and 0.22μm polytetrafluoroethylene organic phase microporous membrane Filter, and filter the extract into a small sample bottle for testing.

[0025] The sample solution to be tested was determined by high performance liquid chromatography. Chromatog...

Abstract

The invention relates to a detection method of textile, in particular to a detection method for PBB (polybrominated biphenyl) and PBDE (polybrominated diphenyl ether) fire retardants in the textile. The method comprises steps as follows: producing standard curve equations; preparing a to-be-detected sample solution; measuring the to-be-detected sample solution by an ultra-high performance liquid chromatograph, and the like, wherein chromatographic conditions are as follows: a chromatographic column is ACQUITY UPLC BEH C18 1.7 mu m, 2.1*50 mm; a mobile phase A is acetonitrile, and a mobile phase B is 5mM ammonium acetate with pH of 4.5; gradient elution is adopted; the column temperature is 40 DEG C; the detection wavelength is 230 nm; the sample introduction volume is 1 mu L. According to the method, 12 PBBs and PBDEs can be effectively and rapidly separated, the chromatographic analysis time does not exceed 10 min, and besides, the method has a better linear relation and is suitable for rapid detection of PBBs and PBDEs in the textile in actual working.

Description

technical field [0001] The invention relates to a detection method for textiles, in particular to a detection method for polybrominated biphenyl (ether) flame retardants in textiles. Background technique [0002] With the development of modern science and technology and the progress of the textile industry, the types of textiles continue to increase, and their application scope continues to expand and extend to all aspects of people's production and life. However, textile materials are generally flammable or combustible, which can easily cause fire accidents. According to statistics, more than 20% of the fire accidents in the world are caused or expanded by the burning of textiles, especially residential fires. Therefore, the flame-retardant function of textiles is extremely important to eliminate fire hazards, delay the spread of fire, and reduce the loss of people's lives and property. In recent years, countries around the world have carried out research on textile flame...
