Résumé: | Mixed chitosan / hydroxyethyl cellulose membranes were prepared and studied, as well as bridged using a crosslinking agent,as a result, this chemical crosslinking structure of the mixed membrane was analyzed by IR and UV-VISIBLE spectroscopy. This work aims to develop a biocomposite in the form of a gel, valuing chitosan and hydroxyethyl cellulose as renewable resources, adding glutaraldehyde as a binding agent, so as to form a hydrophilic matrix that admits to provide a swelling property. Therefore, these mixed membranes are suitable for capturing undesirable substances, and retaining volatile substances in order to prolong the evaporation time. |
