Magnetic solid‐phase extraction using magnetic hypercrosslinked polymer for rapid determination of illegal drugs in urine

“…Then, the precursor was prepared by a precipitation polymerization method [6] with some modification. MPSmodified Fe 3 O 4 /SiO 2 (2.0 g), MAA (1.0 g), DVB (4.0 g), VBC (5.0 g), AIBN (100 mg), and ACN (400 mL) were successively added into a 500-mL three-necked round-bottom flask equipped with a condenser pipe and a stirring device.…”

“…So far, HCPs (with or without enhanced hydrophilicity) have delivered satisfactory results when used as sorbents in SPE to extract several groups of compounds from different samples matrices [6,[11][12][13][14]. However, almost all these reported SPE processes needed to perform a time-costing step of column passing and filtration operation because HCP sorbents were generally packed into SPE cartridges.…”

“…Of all the different types of sorbents available (i.e. silica-, carbon-, and polymerbased sorbents), polymeric materials are one group of the most important sorbents used in SPE, since they offer distinct advantages such as sorbent stability under a very broad pH range of analysis conditions [6].…”
