Preparation of magnetic strong cation exchange resin for the extraction of melamine from egg samples followed by liquid chromatography–tandem mass spectrometry

Application of ion-exchange resin beads to produce magnetic adsorbents

“…Such adsorbent could be a resin combined with magnetic properties in fluidized beds (Feng et al 2000). By using a magnetic adsorbent, the separation from the aqueous medium by applying magnetic field is not just easier, but also faster, selective and efficient (Xu et al 2010;Sharma et al 2018).…”

Jacket-free stir bar sorptive extraction with bio-inspired polydopamine-functionalized immobilization of cross-linked polymer on stainless steel wire

“…Several materials have been developed as sorbents to extract polar compounds in complex matrices, such as organic polymers [6,7], metal oxides [8], ion exchange resins [9,10] and natural macromolecules [11]. Cross-linked organic polymers are used widely in separation science; the polymer can be synthesized conveniently by co-polymerization of functional monomers and cross-linkers in the presence of porogens.…”

Sulfonated polystyrene magnetic nanobeads coupled with immunochromatographic strip for clenbuterol determination in pork muscle

“…Various magnetic materials that contain different surface-functionalized chemical groups have been successfully used to absorb metal ions from polluted water [25][26][27], phenolic compounds from environmental samples [28,29], melamine from egg samples [30], sulfonamides and tetracyclines from milk samples [31], and trace amounts of leuco-malachite green from fish tissue [32]. However, MSPE has yet to be used to extract CLE from tissue samples.…”
