Özet
In this research, molecular imprinting polymers (MIPs) for D-arabinitol were synthesized using a bulk\rpolymerization method through a noncovalent approach. The MIPs were prepared by using D-arabinitol as a template,\racrylamide as a functional monomer, ethylene glycol dimethacrylateas cross-linker, benzoyl peroxide as an initiator and\rdimethyl sulfoxideas a porogen. MIPS was synthesized in several formulas with a different molar ratio of template to\rfunctional monomers and cross-linker. Fourier-transform infrared spectroscopy (FT-IR) and scanning electron microscopy\r(SEM) were used to characterize the MIPs produced. A batch rebinding assay was used to test the binding efficiency of\reach formula. Batch rebinding test results revealed that MIPsF3 with a molar ratio of the template: monomer and crosslinker ratio respectively (1: 4: 25) had the highest binding capacity at 1.56 $mgg ^{?1}$. The results of isotherm adsorption\rshowed that the MIPs produced followed the Freundlich equation with an R-value of 0.97. The MIPs produced was also\rselective toward its isomeric compounds (i.e. L-arabinitol, adonitol, xylitol, and glucose). The extraction efficiency of\rthe MIPs against D-arabinitol was 88.98%.
