Abstract | ||||
Molecularly Imprinted Polymer (MIP) has the ability to selectively bind target molecules so that it can be used as an absorbent in the separation process. This study aims to synthesize, characterize, and analyze the optimization of MIP performance. MIP material is synthesized using the precipitation polymerization method which reacts between methacrylamide (MAM) as a monomer, ethylene glycol dimethacrylate (EGDMA) crosslinker, and dibutyl phthalate (DBP) as a template molecule. MIP material is characterized using SEM-EDS, FTIR spectrometer, SAA, and UV-Vis spectrophotometer. The test variables for the adsorption ability of MIP material to DBP compounds are time and concentration. The results of the study showed that the synthesized MIP is a fine and uniform white solid granule. The results of EDS characterization showed a decrease in the atomic mass of C and the percent of C atoms indicating the extraction of DBP from MIP_DBP_MAM-co-EGDMA(AE). SEM characterization showed a surface morphology of small round grains that tended to be uniform. The functional groups that influenced both polymers obtained from FTIR data were –NH, –CH, –C=C and –C=O. SAA analysis showed that the surface area of MIP_DBP_MAM-co-EGDMA(AE) was 27.6950 m2/g. The optimum time of MIP_DBP_MAM-co-EGDMA(AE) adsorption to DBP was 60 minutes according to the pseudo-second-order kinetic model. The adsorption of MIP_DBP_MAM-co-EGDMA(AE) was in accordance with the Langmuir adsorption isotherm with adsorption capacity values of 2.039 mg/g. The adsorption kinetic model that occurs in MIP follows the pseudo-second-order adsorption kinetic model. | ||||
