Sorbtion of some impurities from aqueous solutions by polymer complex poly(vinylalcohol) with poly(acrylamide) grafted copolymers (PVA-PAAN) was studied by means of spectrophotometry and steady-state fluorescence methods. The experiments showed that the PVA-PAAN films effectively sorbs impurities molecules of average benzene ring from water. Simultaneously, the processes of polymer films dissolving in water take place. The thermal annealing (with the help of special methods) PVA-PAAN film gives a possibility to obtain non-dissolving polymer films which possess high sorbtion ability. Such films are proposed to be used as the sensors with optical response.
