In this paper, a novel molecular imprinted polymer using L-tryptophan(L-Trp) as the template, dopamine(DA) as both functional monomer and cross linking agent, magnetic graphene as the supporting matrix was synthesized. The prepared magnetic-graphene molecularly imprinted polymers(Fe3O4@GO-MIPs) were characterized by Fourier transform infrared spectrometer(FT-IR), transmission electron microscopy (TEM), vibrating sample magnetometer (VSM), respectively. The results showed that when the molar ratio of L- tryptophan and dopamine was 1:4 and the reaction temperature was 60 °C, Fe3O4@GO-MIPs had the best adsorption quantity of 31.9 mg/g. The rebinding experiments indicated that Fe3O4@GO-MIPs not only have outstanding affinity and selectivity towards L-Trp over structurally related compounds but also easily reach the magnetic separation under an external magnetic field.
