Imprinted Polymer of Bisphenol A Glycerolate Dimethacrylate/formaldehyde (Bis-GMA/FA) was synthesized using bisphenol A glycerolate dimethacrylate (Bis-GMA) (functional monomer), triethylene glycol-dimethacrylate (TEGDMA) (cross linker) and formaldehyde (FA) as a template molecule via photopolymerization (380 – 515 nm) for 60 seconds. Elimination of template from polymer was done with methanol/acetic acid (9/1) for 8 hours. The FTIR spectrum showed that the broad peak at 1650 – 1750 cm-1 region in Bis-GMA/FA become sharp after washing demonstrating the elimination of excessive carbonyl group (formaldehyde). The surface morphology of Bis-GMA/FA showed the presence of pores as compared to non-imprinted polymer of Bisphenol A Glycerolate Dimethacrylate (Bis-GMANIP). The recognition study demonstrated that Bis-GMA/FA with 0.1% template exhibit higher binding capacity (0.19 mgg-1 ) for formaldehyde as compared to other Bis-GMA/FA and Bis-GMANIP. Freundlich isotherm showed good heterogeneity (n = 0.702) of Bis-GMA/FA and formaldehyde in an aqueous medium. © 2022, Microscopy Society of Malaysia. All rights reserved.
