Public ISBD Titre : Synthesis and characterization of carboxymethylcellulose hydrogels and applicatio, for crystal violet removal from aqueous solution Type de document : texte imprimé Auteurs : Maria rekia Derdoukh, Auteur ; Safa Fettache, Auteur ; Souad Djellali, Directeur de thèse Année de publication : 2022 Importance : 1 vol (61 f .) Format : 29cm Langues : Anglais (eng) Catégories : Thèses & Mémoires:Chimie Mots-clés : Chimie Index. décimale : 540 Chimie et sciences connexes Résumé : In this work, hydrogels based on renewable resources raw materials, namely carboxymethylcellulose (CMC), were elaborated. A cross-linked systems based on CMC are prepared using citric acid as crosslinker then were used for the removal of crystal violet from aqueous solutions. The results indicate that after heating of our systems at 140°C, crosslink systems are obtain and the optimum concentration of citric acid was found to be6% (w/w).The obtention of cross-linked structures were confirmed by SEM images in addition to gel fraction and swelling ratio evaluations. Adsorption tests have shown the great ability of CMC based hydrogel to adsorb the cationic dye Methyl violet.
