This book was released on 2018-05-14 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Langmuir et de Freundlich et celle des ions Al (III) et des substances humiques par l’isotherme de Langmuir. L’étude cinétique a montré que les réactions d’adsorption des ions Mn (II) et Al (III) sont suivies par le modèle du pseudo-second ordre, alors que celle des substances humiques est suivie par le modèle du pseudo-premier ordre et caractérisée par un mécanisme de transfert de masse externe. L’étude thermodynamique a montré que l’adsorption des ions Mn (II) et des substances humiques est spontanée, l’adsorption des ions manganèse est endothermique sur le charbon actif, CAo, et exothermique sur les charbons actifs, CAH et CAZ, alors que celle des substances humique est endothermique à la surface de chaque charbon actif.

Book Synopsis Organic Micropollutants in the Aquatic Environment by : G. Angeletti
Download or read book Organic Micropollutants in the Aquatic Environment written by G. Angeletti and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than 10 years after the "First European Symposium on Organic Micropollutants in the Aquatic Environment", the "Sixth Symposium" was held in Lisbon (Portugal) from 22 to 24 May 1990. The Symposium was organised within the framework of the Concerted Action COST 641 * which is included in the Fourth R&D Programme on the Environment of the Commission of the European Communities expiring at the end of 1990. After restructuring the Concerted Action in 1984, particular attention has been devoted to fate and transformation of organic micropollutants in the aquatic environment. Therefore, a major aim of the Symposium was to review current studies and progress in these areas, besides more general aspects related to analytical methodologies and behaviour of pollutants during water treatment processes. This volume contains the plenary papers presented in the following sessions at the Symposium: - Multidisciplinary studies - Partitioning of organic micropollutants in the aquatic environment - Novel analytical techniques in environmental chemistry - Monitoring micropollutant - Degradation of organic micropollutants during field conditions - Reclamation of polluted ground water - Chemical and photochemical oxidation - Future of environmental chemistry. In addition, extended versions of posters are included, covering the four topics which are dealt within the four Working Parties forming the structure of the Concerted Action: 1. Analytical methodologies 2. Transport and distribution 3. Transformation reactions 4. Water treatment. We believe that the Proceedings give a good overview of current activities in these fields of research in Europe.

Book Synopsis Equilibria and Dynamics of Gas Adsorption on Heterogeneous Solid Surfaces by : W.A. Steele
Download or read book Equilibria and Dynamics of Gas Adsorption on Heterogeneous Solid Surfaces written by W.A. Steele and published by Elsevier. This book was released on 1996-12-17 with total page 909 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fact that the surfaces of real solids are geometrically distorted and chemically non-uniform has long been realized by the scientists investigating various phenomena occurring on solid surfaces. Even in the case when diffraction experiments show a well-organized bulk solid structure, the surface atoms or molecules will usually exhibit a much smaller degree of surface organization. In addition to the results obtained from electron diffraction, this can be seen in the impressive images obtained from STM and AFM microscopies. This geometric and chemical disorder is the source of the energetic heterogeneity for molecules adsorbing on real solid surfaces. Hundreds of papers have been published showing that this heterogeneity is a major factor in determining the behaviour of real adsorption systems.Studies of adsorption on energetically heterogeneous surfaces have proceeded along three somewhat separate paths, with only minor coupling of ideas. One was the study of adsorption equilibria on heterogeneous solid surfaces. The second path was the study of time evolution of adsorption processes such as surface diffusion or adsorption-desorption kinetics on heterogeneous surfaces, and the third was the study of adsorption in porous solids, or more generally, adsorption in systems with limited dimensions. The present monograph is a first attempt to provide a synthesis of the ways that surface geometric and energetic heterogeneities affect both the equilibria and the time evolution of adsorption on real solids. The book contains 17 chapters written by a team of internationally recognized specialists, some of whom have already published books on adsorption.

Download or read book Porous Carbons written by Feiyu Kang and published by Elsevier. This book was released on 2021-11-04 with total page 874 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon materials form pores ranging in size and morphology, from micropores of less than 1nm, to macropores of more than 50nm, and from channel-like spaces with homogenous diameters in carbon nanotubes, to round spaces in various fullerene cages, including irregularly-shaped pores in polycrystalline carbon materials. The large quantity and rapid rate of absorption of various molecules made possible by these attributes of carbon materials are now used in the storage of foreign atoms and ions for energy storage, conversion and adsorption, and for environmental remediation. Porous Carbons: Syntheses and Applications focuses on the fabrication and application of porous carbons. It considers fabrication at three scales: micropores, mesopores, and macropores. Carbon foams, sponges, and 3D-structured carbons are detailed. The title presents applications in four key areas: energy storage, energy conversion, energy adsorption, including batteries, supercapacitors, and fuel cells and environmental remediation, emphasizing the importance of pore structures at the three scales, and the diffusion and storage of various ions and molecules. The book presents a short history of each technique and material, and assesses advantages and disadvantages. This focused book provides researchers with a comprehensive understanding of both pioneering and current synthesis techniques for porous carbons, and their modern applications. - Presents modern porous carbon synthesis techniques and modern applications of porous carbons - Presents current research on porous carbons in energy storage, conversion and adsorption, and in environmental remediation - Provides a history and assessment of both pioneering and current cutting-edge synthesis techniques and materials - Covers a significant range of precursor materials, preparation techniques, and characteristics - Considers the future development of porous carbons and their various potential applications
