Embodiment 1

[0085] Embodiment 1, a kind of gas chromatography-mass spectrometry detection method applicable to salicylate anti-ultraviolet finishing agent in textiles, comprises the following steps:

[0086] 1), prepare the sample solution to be tested

[0087] (1) Take the textile to be tested, cut it into small pieces of about 5mm×5mm, and mix well;

[0088] (2) Weigh 1.0g of the above-mentioned chopped sample, accurate to 0.01g, place it in a glass extractor with a screw cap, add 10mL of methanol to immerse all the samples in the liquid, seal the extractor, and Ultrasonic extraction in a 40kHz ultrasonic generator for 30 minutes;

[0089] The solid-liquid ratio of the sample to be tested and the extractant is: 1g / 10mL;

[0090] (3) After cooling to room temperature, filter the sample liquid with a 0.45 μm filter head, and then place the obtained filtered sample liquid in a sample bottle and seal it for qualitative and quantitative analysis by gas chromatography-mass spectrometry;

Abstract

The invention discloses a gas chromatography-mass spectrometry detection method of salicylate-based UV-resistant finishing agents for textiles, which comprises the following steps: preparing a sample solution to be tested; After the organic solvent is dissolved, a mixed standard working solution is formed; the gradient standard working solution is injected into a gas chromatograph-mass spectrometer, and the electronic bombardment ion source is used for detection in the selected ion monitoring mode to determine the appearance of 7 kinds of salicylate anti-ultraviolet finishing agents. Peak position, record the peak area of ​​the quantitative ion pair, and make a standard curve equation; detect the sample solution to be tested according to the above method, and obtain the contents of the 7 kinds of salicylate anti-ultraviolet finishing agents in the sample to be tested. The gas chromatography-mass spectrometry method is suitable for the detection of salicylate anti-ultraviolet finishing agents in textiles, and has the advantages of qualitative, quantitative and high sensitivity.

Description

technical field [0001] The invention relates to a gas chromatography-mass spectrometry detection method suitable for salicylate anti-ultraviolet finishing agents in textiles. Background technique [0002] Ultraviolet rays can cause tanning, sunburn, and even skin cancer. With the gradual deepening of people's understanding of ultraviolet radiation in the sun and its hazards to human health, people have made great efforts to explore various methods that can reduce the damage of ultraviolet rays to human health. Among them, anti-ultraviolet clothing has become an indispensable equipment for outdoor sports. Clothing fabrics made of natural fibers or conventional chemical fibers generally cannot meet the requirements for anti-ultraviolet radiation. Functional textiles can generally be obtained by applying functional fibers and functional finishing. The principle of protection is to treat fibers, yarns or fabrics with chemical agents with absorption and shielding properties. S...
