Rezumat:

Molecular imprinting is a versatile and ecological method for obtaining polymeric materials with a lot of applications in the field
of pharmacy, medicine and biosensor assays. In this work, a new method of alternative molecular imprinting to design imprinted
poly (vinyl alcohol) films has been proposed. Glycyrrhizinic acid has been used as template molecule. To demonstrate the
obtaining of the molecular imprinted poly (vinyl alcohol) and its selectivity, studies of glycyrrhizinic and glycyrrhetinic acid
sorption and desorption have been done. Also a study of the life cycle of the imprinted material has been performed, and as
secondary valorification, the absorptive capacity of the material for Cu2+ ions has been tested.
