| titleOfInvention | Method for detecting total amount of perfluorooctane sulphonates (PFOS) in textile and leather |
| abstract | The invention discloses a method for detecting total amount of perfluorooctane sulphonates (PFOS) in textile and leather, which sequentially comprises the following steps: solvent extraction of a sample, chemical treatment of extract liquid, purification and liquid chromatogram-mass spectroscopy. According to the invention, as PFOS in the sample are extracted by methanol with assist of ultrasonic wave, the extraction efficiency is high, the effect is obvious, and the operation is simple; a specific chemical cracking treatment is adopted so that the PFOS is decomposed into equivalent octanesulfonic acid and the measurement of perfluorooctane sulfonyl content in PFOS is realized; filler is adopted to purify the chromatographic column of silica gel, and interference of impurities in the extract liquid (oil, dye) on the liquid chromatogram-mass spectroscopy process is effectively reduced; and compared with the prior test technology, the method disclosed by the invention realizes analytical detection on the total amount of PFOS in the sample. |
