In this work, Magnetic molecular imprinting polymers (MMIP) were used to separate recombinant human insulin. Different kinetic models for the adsorption of insulin on MMIPs and magnetic molecular non-imprinting polymers (MNIPs) were investigated. The results were shown that the adsorption capacity (Q, mg.g-1) of the MMIPs, and imprinting factor (IF) are found to be 66.5 mg.g-1, and 3, respectively. Studies demonstrate that the pseudo-second-order model has a better fit (R2= 0.9988) for insulin adsorption kinetics on MMIPs. Moreover, the Elovich confirmed the chemisorption adsorption of insulin on MMIPs (R2=0.998). The characterization of synthesized particles was applied by Fourier transform infrared spectrometry (FT-IR), and the vibrating sample magnetometer (VSM) and the MMIPs achieved rapid magnetic separation (19.93 emu g-1).
