摘要: Molecularly imprinted thin membranes for selective removal of tetracycline from real water samples were prepared using the radiation-induced polymerization method. The chemical and physical characterization was conducted by FTIR, XPS, AFM SEM analyses. effect template on size distribution pores in membrane structure investigated positron annihilation lifetime spectroscopy (PALS) experiments. presence molecule causes formation larger cavities, which have a strong correlation to molecular molecule. density free volume holes network shows significant increase due binding performances tested against various factors such as pH, time initial concentration molecules. specific selectivity cross-reactivity capacity obtained at 14.5 μmol g-1 , with highest imprinting factor (2.84) tetracycline. 1.44, 1.25 1.57 oxytetracycline hydrochloride, doxycycline hyclate chlortetracycline, respectively. capability promising application filter material high capacity. Tetracycline percentage determined 92.4, 81.1., 75.0 68.7 ultra-pure water, tap natural collected different sources,
