Abstract: Novel magnetic ion imprinted polymers based on vinyl-functionlized multiwalled carbon nanotubes (MWNTs@MIIPs) with highly selective adsorption toward Pb2+ were synthesized using Pb2+ as the template, methacrylic acid as the functional monomer and ethylene glycol dimethacrylate as the cross. linker. The MWNTs@MIIPs were characterized by scanning electron microscopy, Fourier-transform infrared analysis and vibrating sample magnetometer analysis. Adsorption studies demonstrated that the MWNTs@MIIPs possessed excellent adsorption and selective recognition ability towards Pb2+ with a maximum capacity of 25. 9 mg/g. And the selectivity factor of MWNTs@MIIPs towards Pb2+/Cu2+, Pb2+/Zn2+ Pb2+/Co2+, Pb2+/Mg2+, Pb2+/Cd2+ and Pb2+/Ni2+ was 2. 3, 2. 5, 2. 1, 2. 2, 2. 1 and 2. 4, respectively. Combined with atomic absorption spectrometric analysis technology, the MWNTs@MIIPs were successfully applied for separation and enrich. ment trace Pb2+ in environmental real samples with the enrichment factor of 40. 5
