Beschreibung
Zusammenfassung:	The invention discloses a porous modified adsorbent for solid-phase extraction, a preparation method thereof and a solid-phase extraction device. The porous modified adsorbent is prepared by sinteringa material comprising thermoplastic polymer resin and a solid-phase extraction adsorbent, wherein the thermoplastic polymer resin is polyethylene (PE) and/or polypropylene (PP) and/or polyvinyl chloride (PVC) and/or polystyrene (PS) and/or polyethylene glycol terephthalate (PET) and/or nylon (PA). The porous modified adsorbent is controllable in pore diameter, high in assembly efficiency, good inproduct uniformity and suitable for solid-phase extraction of viscous and particle-containing samples. 一种用于固相萃取的多孔改性吸附剂、其制备方法及固相萃取装置，该多孔改性吸附剂由包括热塑性聚合物树脂和固相萃取吸附剂的材料通过烧结制成，其中热塑性聚合物树脂为聚乙烯(PE)和/或聚丙烯(PP)和/或聚氯乙烯(PVC)和/或聚苯乙烯(PS)和/或聚对苯二甲酸乙二醇酯(PET)和/或尼龙(PA)。该多孔改性吸附剂孔径可控，装配效率高，产品均一性好，适于粘稠、含颗粒样品的固相萃取。
