Problems solved by technology

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 such as Figure 1-23 Shown is the method for gas chromatography-mass spectrometry determination of chlorobenzene organic pollutants in leather, which may further comprise the steps:

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

[0056] Step 2. Sample extraction. Weigh 1.00 g of the sample, place it in a 40 mL reaction bottle, add 30 mL of dichloromethane, and perform ultrasonic extraction for 30 min at room temperature to obtain an ultrasonic extraction solution. Filter the ultrasonic extraction solution into a 100 mL flat-bottomed flask, concentrate with a rotary evaporator at a temperature of 40°C to obtain a 1-2 mL concentrated solution, transfer the concentrated solution to an evaporating tube, wash the flat-bottomed flask with a small amount of dichloro...

Abstract

The invention discloses a method for measuring chlorobenzene organic pollutants in leather by gas chromatography-mass spectrometry. The method comprises the following steps of preparing a to-be-measured sample, extracting a sample, confecting a standard working solution and detecting a to-be-measured sample solution. According to the method, the ultrasonic extraction-gas chromatography-mass spectrometry is combined; the chlorobenzene organic pollutants in the leather can be measured at the same time; the method has the advantages of accurateness, quickness and high sensitivity; the reliable detection method support is provided for the quick detection of the leather.

Description

technical field [0001] The invention belongs to the field of leather detection and relates to gas chromatography-mass spectrometry (GC-MS), in particular to a gas chromatography-mass spectrometry method for measuring chlorobenzene organic pollutants in leather, and is especially suitable for leather. Background technique [0002] With the improvement of people's living standards and the enhancement of environmental awareness, green consumption has become a trend. The carrier dyeing process is a commonly used dyeing process in the leather goods industry. Carrier dyeing is beneficial to dyeing leather products with disperse dyes under atmospheric pressure boiling dyeing conditions. Some inexpensive chlorine-containing aromatic compounds, such as dichlorobenzene, trichlorobenzene, and tetrachlorobenzene, are efficient dyeing carriers. These chlorobenzene carriers are used in the dyeing process of leather goods to help the expansion of fiber structure and the penetration of dy...
