Document Type and Number:
WIPO Patent Application WO/2020/087209
Kind Code:
A1
Abstract:
Disclosed are a porous modified adsorbent for solid-phase extraction, a preparation method therefor and a solid-phase extraction device. The porous modified adsorbent is prepared by sintering materials comprising a thermoplastic polymer resin and a solid-phase extraction adsorbent, wherein the thermoplastic polymer resin is a polyethylene (PE) and/or polypropylene (PP) and/or polyvinyl chloride (PVC) and/or polystyrene (PS) and/or polyethylene terephthalate (PET) and/or nylon (PA). The porous modified adsorbent has controllable pore diameters, a high assembly efficiency and good product uniformity, and is suitable for solid-phase extraction of viscous samples containing particles.
