Zusammenfassung: | The invention relates to a method for rapidly separating polycyclic aromatic hydrocarbons in textiles by using supercritical CO2 fluid. The method is a method for separating polycyclic aromatic hydrocarbons in a short time by using a supercritical fluid extraction technique; the method is researched and invented to solve the defects that the separation time of polycyclic aromatic hydrocarbons in the textiles is long, a high quantity of organic solvents are used, the organic solvents are toxic and are not environmental-friendly in the prior art. The method has the advantages of rapid speed, high reproducibility, simplicity in operation, low consumption of organic solvents and no pollution to environment. According to the technical scheme, the method is combined with a gas chromatograph-mass spectrometer, a gas chromatograph or a liquid chromatograph in use, and is capable of rapidly separating and detecting the polycyclic aromatic hydrocarbons in the textiles.
