Molecular imprinted polymeric membrane for naringin recognition

Membranes of poly(acrylonitrile co-acrylic acid) made by phase inversion
technique in the presence of naringin showed molecular recognition
behaviour towards the template molecule. The interactions of the
carboxylic groups of the polymer chain played an important role in the
discrimination process. Simple prolonged washing with ethanolic acetic
acid solution regenerated the membrane without any loss of the binding
capacity. No recognition properties were detected for membranes made
without the imprinted molecule.
