Porous polymer networks of
N
-vinylpyrrolidone with triethylene glycol dimethacrylate were prepared by three-dimensional radical copolymerization using template approach based on incorporation of macromolecular nanoobjects with porogen function. The adsorption of Rose Bengal dye from aqueous solutions onto the copolymers prepared and its desorption were studied by electronic absorption spectroscopy. The specific surface area of the porous polymer networks was estimated from the Rose Bengal adsorption data. The porous polymer networks adsorb riboflavin from aqueous solution. The riboflavin desorption is characterized by complex pattern due to washout from pores of different size.
