Etude expérimentale et conformationnelle d’un hydrogel à base de cellulose: Application à la dépollution des eaux usées par un colorant.

Abstract

The present work consists in the elaboration and characterization of an interpenetrating network based on a natural polymer (cellulose) and a synthetic polymer poly (hydroxyethyl acrylate), the IPN network is prepared by UV photopolymerization. The work is fundamental but may have application in the field of wastewater treatment (colored). The swelling / deflating behavior of IPN in solutions of colored and unstained water is studied according to the nature of the dyes (cationic "Malachite Green") and (anionic "Eosine Y and Orange telon"). Experimental results show the good retention of VM by our IPN (cellulose / polyHEMA) and the low retention for Eosin Y and Orange telon. A conformational study of a system model (IPN / dye) made it possible to highlight the interactions existing between the atoms of the model of the IPN and those of the dyes considered. Molecular doching results from the model chosen for the USCF Chimera program confirm the experimental results.
