Synthesis and Characterization of Magnetic Molecularly Imprinted Polymer for Aniline Recognition

Abstract

Aniline, the main representative of aromatic amines, occursin a large number of industries, such as the production of textiles, plastics, medicines, pesticides, rubber, and varnishes. 1 Due to practicality and efficiency, a molecularly imprinted polymers (MIPs) can be used as sorbents for removing aniline.2 In this study, magnetic molecularly imprinted polymer was synthesized via suspension copolymerization while characterization was performed by various methods in order to obtain an efficient sorbent for the aniline removal from an aqueous solution. Fourier transform infrared spectroscopy (FT-IR) confirmed characteristic vibrational bands which suggested successful synthesis of MIP, nitrogen gas adsorptiondesorption measurements as well as mercury porosimetry have shown that the most dominant pores were mesopores, while scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX) confirmed a 3D spherical porous structure with all the expected elements.
