Molecularly imprinted polymers (MIPs) as well non-imprinted (NIPs) were synthesized for selective sorption of lead and terbium. The ratio raw monomers the terbium–MIPs’ synthesis was optimized based on results lead–MIP. It found that molar template/monomer/monomer/cross-linker = 1:5:5:8 most accurate successful target MIP. As a result, yields MIP NIP terbium 59.3% 61.2%, respectively. structure samples determined by FTIR spectroscopy. SEM analysis structures showed Tb–MIP contained large number pores compared to NIP. size these ranged from 0.779 μm 1.874 μm. experiments adsorption efficiency seven times higher than NIP: degree 70.80% 9.95% imprinting factor calculated equal 7.06. process described Radushkevich pseudo-second-order kinetic models. shown occurred with fast saturation lower Tb concentration, MIP’s passed slower more efficiently. desorption degrees 90.15% 52.67%,
