Preparation and application of caffeic acid imprinted polymer
نویسندگان
چکیده
In the present study, molecularly imprinted polymers were synthesized using caffeic acid (CA) as a template molecule and then used for extraction of CA chlorogenic (CLA) from complex matrices. Syntheses carried out in tetrahydrofuran porogenic solvent 4-vinyl pyridine, methacrylic acid, acrylamide, 1-vinyl imidazole monomers, ethylene glycol dimethacrylate crosslinker 2,2'-azobisisobutyronitrile initiator. polymerization processes, different ratios template:monomer:crosslinker (T:M:CrL) to obtain most suitable polymer. Caffeic acid:4-vinylpiridine:ethylene dimethacrylate's 1:4:16 mole ratio MIP was determined convenient polymer recognition. addition, nonimprinted (NIPs) without templates prepared. Dynamic static adsorption tests applied determine absorption features NIPs CA-MIPs. Separation purification studies CLA performed with molecular solid phase (MISPE) application. All steps MISPE (loading, washing, elution) optimized by HPLC analysis.
