About the Book

Thèse de Doctorat de l'année 2016 dans le domaine Chimie - Généralités, Université des sciences et techniques de Masuku (Université des Sciences et Techniques de Masuku de Franceville-Gabon, Ecole Doctorale des Sciences Fondamentales et Appliquees), langue: Français, résumé Ce travail a eu pour thème central les charbons actifs, un adsorbant jouant un rôle fondamental dans l'élimination en solution aqueuse des cations Mn (II) et Al (III), puis des substances humiques. Dans le souci de valoriser les déchets des coques de noix de coula edulis (noisetier d'Afrique), la première phase de cette étude a été consacrée à la préparation et à la caractérisation physico-chimique des charbons actifs. Les propriétés surfaciques étudiées à l'aide de l'Infrarouge à Transmission de Fourier (IRTF), titrage de Boehm, la détermination du pHPCN et l'évaluation des surfaces spécifiques par adsorption de l'iode, le bleu de méthylène et/ou l'acide acétique. Les résultats des spectres infrarouges ont montré respectivement la présence des groupements -C-C-, -C-O-, -C = C- et -C = O. La titration de Boehm a prouvé que l'acidité totale était supérieure à basicité totale. Les valeurs de pH de charge zéro ont été inclus entre 2 et 3,5. Les surfaces spécifiques obtenues par adsorption diminué dans l'ordre de l'iode, l'acide acétique et le bleu de méthylène classant par ordre de prépondérance les micro, méso et macro pores sur leurs surfaces. Enfin l utilisation des charbons actifs obtenus pour éliminer les cations Mn (II) et Al (III), puis les substances humiques en solution aqueuse en mode batch en faisant varier les paramètres tels que le pH, la concentration initiale, le temps de contact, la température, la masse du charbon actif et sa granulométrie. Ces résultats ont révélé que l'adsorption des ions Mn (II), Al (III) et des substances humiques est fortement dépendante du pH. Les données expérimentales ont montré que l'adsorption des ions Mn (II) est suivie par les isothermes de Lang
