  • METHOD AND DEVICE FOR SYNCHRONOUS EXTRACTION AND ANALYSIS OF MULTIPLE TRACE EMERGING ORGANIC CONTAMINANTS IN HAIRS, AND APPLICATION
    Publication number: 20240201176
    Abstract: A method for synchronous extraction and analysis of multiple trace emerging organic contaminants in hairs, and application comprises the following steps: S1, pretreatment; S2, mixing and extraction; S3, nitrogen blowing concentration and purification; and S4, low-temperature separation. A device for synchronous extraction and analysis of multiple trace emerging organic contaminants in hairs, and application comprises comprises a treatment barrel, a pedestal and a drive assembly. This method is applied to a study on long-term exposure of multiple organic contaminants in a human body. According to the present disclosure, an extraction solution extracting system is established, 5 emerging organic contaminants in hairs can be purified and analyzed by establishing a dispersion solid-phase extraction filler consisting of Na2SO4 powders and C18 powders.
