Abstract

See full text

The present invention relates to the field of solid-phase extraction, and particularly to a solid-phase extraction material, and a preparation method and use thereof. The preparation method includes prepolymerizing the monomers N-vinylpyrrolidone and divinylbenzene in the presence of a chain transfer agent, adding prepolymer dropwise to an emulsion of monodispersed seed microspheres, swelling, and reacting to prepare white spheres; and functionalizing the white spheres, to obtain the solid-phase extraction material. The solid-phase extraction material prepared by the reaction has good spherical morphology, large specific surface area, and high ion exchange capacity. The prepared solid-phase extraction material functions in the separation and enrichment of PPCPs by means of a variety of forces with a high extraction rate. The extraction rate is basically maintained between 85% and 105%, and acidic, alkaline, neutral and amphoteric substances is capable of being selectively separated.
