磁性碳纳米管表面多金属离子印迹聚合物制备及应用
Preparation and Application of Magnetic Multi-ion Imprinted Polymers Based on Multiwalled Carbon Nanotubes
摘要
Abstract
Novel magnetic multi-ion imprinted polymers(MIIPs) were synthesized using magnetic multi-walled carbon nanotubes as the supporting materials, Co2+, Cu2+ and Cd2+ as the multi-template and dopamine as the functional monomer.The MIIPs were characterized with Fourier-transform infrared spectrometry, transmission electron microscope, scanning electron microscope and vibrating sample magnetometer in details.Adsorption performance of the MIIPs was investigated by magnetic solid phase extraction and atomic absorption spectroscopy.The results reveal that the MIIPs have outstanding magnetic property, high adsorption capacity, high selectivity and fast binding kinetics toward Cu2+, Co2+and Cd2+ with the maximum adsorption capacity of 46.08 mg/g, 36.35 mg/g and 30.65 mg/g, respectively.Combined with atomic absorption spectroscopy, MIIPs were successfully used to separate and enrich Cu2+, Co2+and Cd2+ in real sludge samples with the enrichment factor of 18.6, 13.4 and 10.9, respectively.关键词
