The invention provides a solid-phase extraction method of perfluorinated compounds in environmental water, which comprises the preparation steps of a solid-phase extraction column; in the step, a dopamine-modified graphene oxide composite material (DA-GO) is used as a filler to prepare a solid phase extraction column, a sample is collected, a solid phase extraction step and a volume fixing step. In the invention, a dopamine-modified graphene oxide composite material (DA-GO) is used as a filler in the solid-phase extraction column to increase the electrostatic attraction between the solid-phase extraction material and target molecules, thereby further improving the extraction effect. |
