Magnetic molecularly imprinted polymer (MMIP) was prepared against di-(2-ethylhexyl)phthalate, using methacrylic acid as a functional monomer, ethylene glycol dimethacrylate as a crosslinker and benzoyl peroxide as an initiator. MMIP was characterized using Scanning Electron Microscope and infrared spectrophotometer. IR spectrum shows successful preparation of MMIP. The peak at 586 cm−1 is a typical vibration of Fe-O. The strong peaks at 1728 cm−1, 1261 cm−1, and 1153 cm−1 are stretching vibration of C=O and C-O of methacrylic acid and DEHP. The peak at 1462 cm−1 due to C-C aromatic vibration of DEHP. A broad absorption band at 3468 cm−1 due to the stretching vibration of hydroxyl bonds between target molecule and functional monomer. The MMIP has a spherical morphology and pores that important for adsorption process. Experimental results show the potential of magnetic molecularly imprinted polymer for recognition of di-(2-ethylhexyl) phthalate.
