- Scope
- This section is applicable to the extraction of semi-volatile organic compounds that are insoluble or slightly soluble in water in soil and sediments, including organophosphorus pesticides, organochlorine pesticides, chlorinated herbicides, polychlorinated biphenyls (PCBs), polychlorinated dibenzo Para-dioxins and polychlorinated dibenzofurans (PCDDs/PCDFs), total petroleum hydrocarbons, diesel and waste oil, etc. The extraction efficiency is higher for dry objects with small particles, so it is best to air-dry and grind the sample before extraction. The sampling amount is generally 10~30g, and the sampling amount can be increased or decreased appropriately according to the actual situation.
