Magnetic molecularly imprinted polymers (MMIPs) were synthesized for selective recognition and rapid enrichment of indole from a model fuel. The MMIPs were synthesized by precipitation polymerization and a surface molecular imprinting technique, using indole as the template molecule, FC3O4 nanoparticles as magnetically susceptible components, methylacrylic acid as the functional monomer, and ethylene glycol dimethacrylate as a cross-linker. The properties of the MMIPs were characterized by Fourier-transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy, vibrating sample magnetometry, and thermogravimetric analysis. The adsorption capacity of indole-molecularly imprinted polymers (MIPs) was 50.25 mg g(-1) at 303 K and reached adsorption equilibrium in a short time. Experimental data were modeled with a pseudo-second-order, Langmuir isotherm model. The selective adsorption performance of MIPs was favorable. (C) 2015Wiley Periodicals, Inc.
