Dispersive micro solid phase extraction of glibenclamide from plasma, urine, and wastewater using a magnetic molecularly imprinted polymer followed by its determination by a high-performance liquid chromatography-photodiode array detector

“…[17][18][19][20] Dispersive magnetic solid phase extraction (DMSPE) is an MSPE mode in which the magnetic sorbent is directly dispersed into sample solutions, resulting in enhanced effective interfacial area between the analytes and sorbent and better mass transfer, which alleviates the possibility of high pressure and frequent column blocking encountered in SPE. 21 Furthermore, magnetic sorbents can be easily reused and recycled, making them both cost-effective and eco-friendly. 22,23 Until now, different non-magnetic or magnetic sorbents, such as S@SnO 2 -NPs, 13 Fe 3 O 4 @PPy NPs, 24 CoFe 2 O 4 / MCM-48/chitosan, 25 and SiO 2 -coated Fe 3 O 4 , 26 have been utilized for SPE of glibenclamide from various media.…”
