Synthesis and Evaluation of Molecularly Imprinted Polymer As a Selective Material for Vanillin
Keywords:Vanillin, Molecularly imprinted polymer, Selective material
Molecularly imprinted polymers (MIPs) using vanillin (Val) as a template molecule were synthesized and evaluated. MIPs were prepared by precipitation polymerization using various types of functional monomers with using ethylene glycol dimethacrylate (EGDMA) and trimethylolpropane trimethacrylate (TRIM) as cross linkers and polymerization was done at 80°C for 6 h. The binding efficiency of polymers was evaluated including types of monomers, binding time and reusability. Results showed that methacrylic acid was the selective monomer for vanillin and the highest performance of MIPs, which including the binding efficiency and selectivity, was obtained when bound polymer with vanillin for only 2 h and could be reused as least five times.
