Abstract: A molecularly imprinted polymer (MIP) using benzoic acid as template molecule, 4-vinyl pyridine (4-VP) as functional monomer, ethylene dimethacrylate (EDMA) as cross-linker, was prepared by bulk polymerization. The needle-type gas concentrator was developed using the MIP as adsorption medium. The device was coupled with gas chromatography (GC) for the analysis of volatile organic compounds (VOCs). The effect of polymerization conditions on adsorption property, such as polymerization time, ratio of the reagents, pre-polymerization time, type of solvents, type of template molecules, has been evaluated. The results of gas chromatographic analysis demonstrated that the optimum conditions for getting the best adsorption performance of the synthesized were polymerization time 6 h at 60 degrees C, the ratio of the reagents (template molecule : functional monomer cross-linker) 1: 4: 20, pre-polymerization time of 3 h, acetonitrile as solvent, benzoic acid as template
Template and target information: benzoic acid, volatile organic compounds, VOCs
Author keywords: molecularly imprinted polymer, benzoic acid, Bulk polymerization, Needle-type gas concentrator, gas chromatography
