Résumé: | This work consists in identifying dyes in water solutions, prepared with different concentrations and in proposing a method for retaining these coloring molecules by crosslinked networks of hydrophilic acrylic polymers poly (hexylethylmethacrylate) [poly (HEMA)]. The crosslinked poly (HEMA) networks were prepared by UV photo polymerization. The swelling and deswelling behavior of the poly (HEMA) network in colored water solutions is studied as a function of the concentration of the dye in the water and the nature of the dye (Eosin and Malachite Green). The results show the retention of the dye by the poly (HEMA) network in all the cases studied. The exploitation of the experimental results of the kinetics of swelling by theoretical models shows a good correlation. A conformational study of a model of the poly (HEMA) / dye network system made it possible to highlight the interactions existing between the atoms of the network model and the atoms of the dye considered. The molecular docking results of the polymer / dye network model chosen for the USCF Chimera program confirm that the dye is adsorbed (retained) by the polymer network. |
