Molecular imprinting technology is a convenient approach for preparing synthetic receptors that possesses user defined recognition properties. Oxalic acid imprinted bulk polymer was synthesized by thermal initiated free radical co-polymerization of oxalic acid (template) with two different functional monomers (acrylamide and methacrylic acid) and ethylene glycol dimethacrylate as crosslinker, using acetonitrile (porogen) as solvent. Scanning electron microscopy and FT-IR spectra confirmed the formation of molecularly imprinted polymer (MIP) with acrylamide. The synthesized MIP(ACR) efficiently adsorbed oxalic acid from aqueous solutions. The binding parameters of molecularly imprinted polymer and non-imprinted polymer were compared by Langmuir-Freundlich adsorption (LF) isotherm. © (2013) Trans Tech Publications, Switzerland.
