| abstract |
The invention provides a method for analyzing phthalates, comprising the steps of: providing a liquid sample or a solid sample; pretreating the liquid sample or the solid sample to obtain an extract, wherein the pretreatment method comprises a liquid phase Phase extraction (LLE), ultrasonic assisted extraction (UAE), microwave assisted extraction (MAE), dispersion liquid microextraction (DLLME), condensed dispersion liquid microextraction (DLLME-SFO) or mist point extraction (CPE); The extract is sent to a capillary liquid chromatograph and an ultraviolet/visible spectrometer for detection to analyze phthalates in the liquid sample or the solid sample. |
