Embodiment 1

[0077] Embodiment 1, a liquid chromatography-tandem mass spectrometry detection method suitable for salicylate UV-resistant finishing agents in textiles, the following steps are carried out in sequence:

[0078] 1), prepare the sample solution to be tested

[0079] (1) Take the textile to be tested, cut it into small pieces of about 5mm×5mm, and mix well;

[0080] (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 20mL of methanol to immerse all the samples in the liquid, seal the extractor, and Ultrasonic extraction in a 40kHz ultrasonic generator for 30 minutes;

[0081] The solid-liquid ratio of the sample to be tested and the extractant is: 1g / 20mL;

[0082] (3) After cooling to room temperature, filter the sample liquid with a 0.22 μm filter head, and place the obtained filtered sample liquid in a sampling bottle to seal for qualitative and quantitative analysis by ultra-high performance liquid ch...

Abstract

The invention discloses a liquid mass spectrometry detection method for textile salicylate anti-ultraviolet finishing agents, which comprises the following steps: preparing a sample to be tested into a sample solution to be tested; The gradient standard working solution is prepared into a gradient standard working solution; the gradient standard working solution is injected into the liquid chromatography-tandem mass spectrometer, the positive and negative ion multiple reaction monitoring mode is measured, and the standard curve equation is made; the sample solution to be tested is detected according to the above method, so as to obtain the Contents of 7 kinds of salicylate anti-ultraviolet finishing agents in samples. The liquid chromatography-tandem mass spectrometry method is qualitative, quantitative, and highly sensitive, and is suitable for the detection of salicylate UV-resistant finishing agents in textiles.

Description

technical field [0001] The invention relates to a liquid chromatography-tandem 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 prop...
