Scope

The main technical content: Using Soxhlet extraction or pressurized fluid extraction methods to extract DP from soil and sediments, with dichloromethane as the extraction solvent. After concentrating the extract and removing sulfur, the solution is purified using a multi-layer silica gel column. The target compounds are detected by gas chromatography-mass spectrometry. The qualitative analysis is based on the retention time, fragment ions, mass-to-charge ratio, and abundance ratio of the target compounds in the sample, and the quantitative analysis is carried out using the internal standard method.
