Determination of chloramphenicol in urine, feed water, milk and honey samples using molecular imprinted polymer clean-up

Novel pitaya-inspired well-defined core–shell nanospheres with ultrathin surface imprinted nanofilm from magnetic mesoporous nanosilica for highly efficient chloramphenicol removal

“…However, these obtained imprinted adsorbents based onto mesoporous silica commonly had some problems, such as poor and irregular morphology (inevitable decrease in reproducibility), the very thick imprinted polymer layer (slow adsorption kinetics). Besides, the CAP-MIPs have been prepared already and mainly applied as solid phase extraction adsorbents for selective extraction of CAP from environmental samples [23][24][25][26]. However, these MIPs prepared by conventional methods had less effective binding sites, due to the binding sites deep buried in cross-linking polymer matrix.…”

Ionic liquid-molecularly imprinted polymers for pipette tip solid-phase extraction of (Z)-3-(chloromethylene)-6-flourothiochroman-4-one in urine

“…The condition of Al 2 O 3 , silica, HLB, MCX, C 18 , NH 2 , and IL-NIPs referred to previous reports [34][35][36][37][38][39]. The loading sample was 1 mL of spiked urine (5 g mL −1 ).…”

Multiresidue method for the determination of pharmacologically active substances in egg and honey using a continuous solid-phase extraction system and gas chromatography–mass spectrometry

“…The hydrophilic-lipophilic balanced sorbent Oasis HLB is the most widely used for extracting polar and nonpolar pharmaceutical compounds (Bohm, Stachel, & Gowik, 2012;Deng et al, 2011;Garrido Frenich, del Mar Aguilera-Luiz, Martínez Vidal, & Romero-González, 2010;Martinez Vidal et al, 2009;Sánchez-Brunete, Albero, Miguel, & Tadeo, 2005). Other sorbents such as silica (Courant et al, 2007(Courant et al, , 2008, Strata-X (Ashwin, Stead, Taylor, Startin, & Richmond, 2005), RP-C18 (Rejtharová & Rejthar, 2009) and molecularly imprinted polymers (Blasco & Picó, 2012;Rejtharová & Rejthar, 2009) have also been used for the SPE of PASs from eggs and honey. Alternative, less common sample preparation techniques for the determination of PASs in eggs include pressurized liquid extraction (Runnqvist et al, 2010), solid-phase microextraction (Huang, Zhang, & Feng, 2006) and matrix solid-phase dispersion (Garrido Frenich et al, 2010. A variety of chemically based analytical strategies for determining PASs in eggs and honey have recently been reported.…”
