| titleOfInvention | A kind of analysis method of polycyclic aromatic hydrocarbon content in plant leaves |
| abstract | The invention relates to the technical field of substance detection, and specifically discloses a method for analyzing the content of polycyclic aromatic hydrocarbons in plant leaves. It is acetonitrile; the C18 solid phase extraction cartridge is used to activate the extract to obtain an activation solution; the activation solution is used to measure the polycyclic aromatic hydrocarbons in the activation solution by gas chromatography-mass spectrometry. In the present invention, acetonitrile is used as the extraction solvent when the plant leaf powder is extracted, the prepared extract contains less interfering impurities, the step of saponification can be omitted, labor and time costs are reduced, PAHs loss is reduced, and the operation is simple and economical. Time and analysis speed is fast, which greatly improves the efficiency of determination and analysis, and the detection sensitivity is high, which is suitable for the detection of plant leaves with a sample volume of less than 1g. |
