Abstract

Molecularly Imprinted Polymers (MIP) is a synthetic functional material that can recognize target molecules selectively. This study aims to synthesize and characterize MIP and its performance by precipitation polymerization method using methacrylic acid (MAA), ethylene glycol dimethacrylate (EGDMA), and di-(2-Ethylhexyl) phthalate (DEHP). Characterization of MIP was conducted by FTIR, SEM-EDS, SAA, and UV-Vis spectrophotometer. The effect of concentration and time on MIP adsorption ability against DEHP was also determined. SEM shows that MIP_DEHP_MAA-co-EGDMA surface morphology is arranged from more uniform, less tight, and more fine granules than NIP_MAA-co-EGDMA. FTIR characterization of MIP and NIP (Non-Imprinted Polymers) shows absorption bands of functional groups were –OH, C-H, C=O, and –C=C. SAA characterization shows MIP surface area is 137.660 m2/g, total pore volume 0.1555 cc/g, and an average pore radius 22.59 Å that indicates as mesopore material. MIP_DEHP_MAA-co-EGDMA (AE) adsorbed DEHP better than NIP_MAA-co-EGDMA. The difference value of the adsorbed DEHP (qe) was 0.212 mg/g
