Title:Preparation,Characterization,andAdsorptionPerformanceofHydrophilicMolecularlyImprintedMicrospheresforEugenolEsters
Abstract:
Thedevelopmentofmolecularlyimprintedpolymers(MIPs)withhighselectivityandaffinityfortargetmoleculeshasgainedsignificantattentioninthefieldofadsorptiontechnology.Inthisstudy,hydrophilicmolecularlyimprintedmicrospheresforeugenolesterswerepreparedandcharacterized.Theadsorptionperformanceofthesynthesizedmicrosphereswasinvestigated.
1.Introduction:
Eugenolesters,atypeofnaturalflavorcompoundfoundinvariousplants,possessexcellentantimicrobial,antioxidant,andanti-inflammatoryproperties.Thesecompoundshavegainedconsiderableimportanceinthefoodandpharmaceuticalindustries.However,theseparationandpurificationofeugenolestersfromcomplexmixturesremainchallenging.Molecularlyimprintedpolymers(MIPs)offerapotentialsolutionfortheselectiveextractionandseparationofeugenolesters.
2.ExperimentalSection:
2.1Materials:
Thematerialsusedforthepreparationofhydrophilicmolecularlyimprintedmicrospheresincludedeugenolesters(templatemolecule),acrylamide(monomer),N,N'-methylenebisacrylamide(cross-linker),ammoniumpersulfate(initiator),methacrylicacid(functionalmonomer),ethyleneglycoldimethacrylate(porogen),andcyclohexane(solvent).
2.2PreparationofHydrophilicMolecularlyImprintedMicrospheres:
Thehydrophilicmolecularlyimprintedmicrosphereswerepreparedfollowingaprecipitationpolymerizationmethod.Theeugenolesterswerefirstdissolvedinmethacrylicacidandthenmixedwithacrylamide,N,N'-methylenebisacrylamide,andethyleneglycoldimethacrylate.Themixturewasthenaddedtoacyclohexanesolutioncontainingammoniumpersulfate.Thepolymerizationreactionwasinitiatedbyheatingthesolutionataspecifictemperatureforacertainperiod.Finally,theobtainedmolecularlyimprintedmicrosphereswerewashedanddried.
2.3Characterization:
