| titleOfInvention | A kind of extraction method of perfluorinated and polyfluorinated compound |
| abstract | The invention provides an extraction method for perfluorinated and polyfluorinated compounds. The extraction method of the perfluorinated and polyfluorinated compounds comprises the following steps: (1) under alkaline conditions, after using an organic reagent to leach the target compound in the environmental solid sample, adjust the pH and separate to obtain the extract; ( 2) Utilize the SinCHERS column to purify the extract, and complete the preparation of the sample detection solution; (3) Detect and quantify the target compound by high-performance liquid chromatography-mass spectrometry. The extraction method of the invention effectively improves the extraction efficiency of perfluorinated and polyfluorinated compounds in solid samples such as soil, atmospheric particles, sediments/sludge, shortens the extraction time, and reduces the extraction cost. |
