Abstract :Penicillin G imprinted membranes were prepared by utilizing UV induced in-situ polymerization. The characterization of membranes was conducted by using ATR-FTIR, XPS, SEM and AFM. The binding properties of imprinted membranes were evaluated against concentration and time. The binding capacity of the membranes was tested for real water samples. The size of the binding cavities of membranes was determined by using PALS. The specific selectivity of the membranes was investigated by using similar ß-lactams, penicillin V and amoxycillin. The specific binding of the membranes was de-termined as 3.27 µg/g for penicillin G while this value was obtained as 0.83 and 0.51 µg/g for pencillin V and amoxycillin, respectively. The binding capacity of the membrane was determined as 5.03 µg.g-1 for ultra pure water while this value was obtained as 4.01 µg.g-1 and ~3.50 µg.g-1 for tap water and natural water samples from different sources, respectively.Keywords : Membrane, Molecularly Imprinted Polymer, Penicilin G.
