Method for measuring phenolic compounds in textiles and leather products

Abstract

The invention discloses a method for measuring phenolic compounds in textiles and leather products and relates a method for measuring phenolic compounds in textiles and leather products by using a high efficiency liquid chromatography-triple quadrupole mass spectrometer. According to the method disclosed by the invention, with methanol as an extracting solvent, the phenolic compounds in the textiles and leather products are extracted by adopting an ultrasonic extraction method; if interference of impurities exists, an obtained extracting solution is subjected to solid-phase extraction and purification and is subjected to volume settling by using methanol, and therefore the peak area is quantified by using qualitativeness of relative retention time and multiple reaction monitor. The method disclosed by the invention is rapid and reliable, high in flux analysis, sensitivity and recovery rate and good in precision and can be used for carrying out analysis and measurement on 10 types of phenolic compounds within 12 minutes, and the use amount of reagents is low and only 2.4ml; use of a great deal of chemical reagents is avoided, and therefore the environmental pollution is reduced; and the method is easy and feasible to measure the phenolic compounds in the textiles and leather products.

[0003] Pentachlorophenol, 2,3,4,5-tetrachlorophenol, 2,3,4,6-tetrachlorophenol, 2,3,5,6-tetrachlorophenol, 2,4,5-trichlorophenol, 2,4,...

AI Technical Summary

Problems solved by technology

[0004] Among many detection methods, the determination of pentachlorophenol and 2,3,5,6-tetrachlorophenol, o-phenylphenol and 2-naphthol in leather and textiles is mostly carried out by gas chromatography-electron capture detector (GC- ECD) and gas chromatography-mass spectrometry (GC-MS) detection, and high-performance liquid chromatography-diode array detector (HPLC-DAD) and high-performance liquid chromatography-mass spectrometry (HPLC-MS) for the determination of textiles and Tetrachlorophenol and pentachlorophenol in leather have been reported, but there is no method for the simultaneous detection of these ten phenolic compounds by high performance liquid chromatography-triple quadrupole mass spectrometry (HPLC-MS / MS)
