摘要
Adenine molecular imprinted polymethacrylic acid (PMAA) was in situ prepared on the surface of silica (SiO2) microspheres, constituting a thin and rough molecular imprinted polymer (MIP) layer as characterized by SEM, TEM and FT-IR. Dynamic method and competitive adsorption experiments were used to investigate the adsorption kinetics, adsorption isotherms, selective recognition and adsorption reproducibility of MIP-PMAA/SiO2 particles toward adenine. The results showed that the obtained particles have strong selective affinity, specific recognition and excellent reusability for adenine. MIP-PMAA/SiO2 particles were further used as stationary phase for high performance liquid chromatography (HPLC) and separation of adenine from other nucleic bases was achieved successfully.
