Abstract
A novel magnetic molecularly imprinted polymer (MMIP) was prepared for the recognition of di(2-ethylhexyl) phthalate, using methacrylic acid as a functional monomer, ethylene glycol dimethacrylate as a crosslinker and benzoil peroxide as an initiator. MMIP was characterized using Scanning Electron Microscope and infrared spectrophotometer. IR spectrum show successfull 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 correspond to the C=O stretching vibration and C-O vibration of methacrylic acid and DEHP. The peak at 1462 cm-1 corresponds to C-C aromatic vibration of DEHP. A broad absorption band at 3468 cm-1 correspond to the stretching vibration of O-H bonds. Experimental results show the potential of magnetic molecularly imprinted polymer for selective recognition of di-(2-ethylhexyl) phthalate.
