Problems solved by technology

[0003] However, studies at home and abroad have shown that the chemical properties of chlorobenzene compounds are very stable, and they are not easy to decompose under natural conditions. Long-term exposure can cause skin allergies, affect the human central nervous system, and then have potential teratogenic and carcinogenic effects on the human body.

Embodiment Construction

[0054] Specific embodiments of the present invention are as follows Figure 1-23 Shown is a method for the determination of chlorobenzene compounds in textiles by ultrasonic extraction-gas chromatography-mass spectrometry, which comprises the following steps:

[0055] Step 1. Preparation of the sample to be tested, take an appropriate amount of textile sample, cut the sample into pieces, the size of the sample is less than 20mm × 20mm, and mix the shredded samples evenly;

[0056] Step 2, sample extraction, weigh 1.00 g of the sample, put it in a 40 mL reaction flask, add 30 mL of dichloromethane, and perform ultrasonic extraction at room temperature for 30 min to obtain an ultrasonic extraction solution. The ultrasonic extract was filtered into a 100 mL flat-bottomed flask, concentrated with a rotary evaporator at a temperature of 40 °C to obtain 1-2 mL of concentrated liquid, transferred to an evaporation tube, and washed with a small amount of dichloromethane. The flat-bott...

Abstract

The invention discloses a method using ultrasonic extraction-gas chromatography-mass spectrum to measure chlorobenzene compounds in textiles. The method includes: preparing a to-be-measured sample, extracting the sample, preparing a standard work solution and detecting a to-be-measured sample solution. The method using ultrasonic extraction-gas chromatography-mass spectrum to measure the chlorobenzene compounds in the textiles has the advantages that the chlorobenzene organic pollutants in the textiles can be measured at the same time, the method is accurate, fast and high in sensitivity, and a reliable detecting method support is provided for the fast detection of the textiles.

Description

technical field [0001] The invention belongs to the field of textile detection and relates to gas chromatography-mass spectrometry (GC-MS), in particular to a method of ultrasonic extraction-gas chromatography-mass spectrometry for determining chlorobenzene compounds in textiles, and is especially suitable for textiles. Background technique [0002] With the improvement of people's living standards and the enhancement of environmental protection awareness, green consumption has become a trend. The carrier dyeing process is a commonly used dyeing process in the textile industry. Carrier dyeing is beneficial to the dyeing of textiles with disperse dyes under normal pressure boiling dyeing conditions. Some inexpensive chlorine-containing aromatic compounds, such as dichlorobenzene, trichlorobenzene, and tetrachlorobenzene, are efficient dye carriers. These chlorobenzene carriers are used in textile dyeing processes to aid in bulking of the fiber structure and penetration of d...
