Synthesis of nanoporous molecularly imprinted polymers for extraction of naringenin compound

* Nanotechnology Research Institute, Babol Noshirvani University of Technology, Babol, Iran
In this research for the first time, an adsorbent based on molecularly imprinted polymers (MIPs) for selective extraction of Naringenin using methacrylic acid (functional polymer), trimethylolpropane trimethacrylate (cross linker), azobisisobutyronitrile (initiator) via precipitation polymerization technique in a ratio (1: 4: 20) were synthesized. After template removal, nanoporous imprinted polymeric lattice was prepared which is able to extract Naringenin as a bioactive compound from the mixtures containing this component. Non-imprinted polymers (NIPs) with the same materials (instead of the template molecule) were synthesized to compare the efficiency of the MIPs. Selectivity of the MIPs for Naringenin has been evaluated. Quercetin as a similar molecule of the template was selected which the binding capacity for Naringenin and Quercetin were 284 mg. g-1 and 70 mg. g-1, respectively. Imaging scanning electron microscope (SEM) was used for morphological studies on the synthesized polymer particles and brannaueremmet-teller (BET) analysis method was applied to measure the porosity, specific surface area and poor diameters of the polymer.
