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.

Available in PDF, EPUB and Kindle. Book excerpt: Adsorption Processes for Water Treatment discusses the application of adsorption in water purification. The book is comprised of 10 chapters that detail the carbon and resin adsorptive processes for potable water treatment. The text first covers the elements of surface chemistry and then proceeds to discussing adsorption models. Chapter 3 tackles the kinetics of adsorption, while Chapter 4 deals with batch systems and fixed fluid beds. Next, the book talks about the physical and chemical properties of carbon. The next two chapters discuss the adsorption of organic compounds and the removal of inorganic compounds, respectively. The eighth chapter presents operational, pilot plant, and case studies. Chapter 9 discusses the biological activated carbon treatment of drinking water, and Chapter 10 covers the adsorption of macroreticular resins. The book will be of great use to both researchers and professionals involved in the research and development of water treatment process.

Book excerpt: Adsorption by Carbons covers the most significant aspects of adsorption by carbons, attempting to fill the existing gap between the fields of adsorption and carbonaceous materials. Both basic and applied aspects are presented. The first section of the book introduces physical adsorption and carbonaceous materials, and is followed by a section concerning the fundamentals of adsorption by carbons. This leads to development of a series of theoretical concepts that serve as an introduction to the following section in which adsorption is mainly envisaged as a tool to characterize the porous texture and surface chemistry of carbons. Particular attention is paid to some novel nanocarbons, and the electrochemistry of adsorption by carbons is also addressed. Finally, several important technological applications of gas and liquid adsorption by carbons in areas such as environmental protection and energy storage constitute the last section of the book. - The first book to address the interplay between carbonaceous materials and adsorption - Includes important environmental applications, such as the removal of volatile organic compounds from polluted atmospheres - Covers both gas-solid and liquid-solid adsorption

This book was released on 2013-11-27 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is intended to provide a systematic presentation of theories concerning the adsorption of metal ions from aqueous solutions onto surfaces of natural and synthetic substances and to outline methods and procedures to estimate the extent and progress ofadsorption. As heavy metals and the problems associated with their transport and distribution are of serious concern to human health and the environment, the materials presented in this volume have both theoretical and practical significance. In writing this monograph, one ofour goals was to prepare a book useful to environmental workers and practicing engineers. For this reason, our presentation relies heavily on concepts commonly used in the environmental engineering literature. In fact, the volume was prepared for readers with a basic understanding of environmental engineering principles and some knowledge of adsorption processes. No prior familiarity with the ionic solute adsorption at solid-solution interfaces is assumed. Instead, introduction of the necessary background information was included. Generally speaking, metal ion adsorption may be studied in terms of three distinct but interrelated phenomena: surface ionization, complex formation, and the formation and presence of an electrostatic double layer adjacent to adsorbent surfaces. Analyses of these phenomena with various degrees of sophistication are xviii ADSORPTION OF METAL IONS FROM AQUEOUS SOLUTIONS presented, and their various combinations yield different models that describe metal ion adsorption.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides practical guidance for the design of liquid and vapor phase devices for the adsorption of organic chemicals. The adsorptive media addressed include granular activated carbon (GAC) and other alternative adsorption carbon media, such as powdered activated carbon (PAC) and non-carbon adsorbents. Adsorption Design Guide addresses various adsorption media types, applicability, use of various adsorption process technologies, equipment and ancillary component design, availability, advantages, disadvantages, regeneration methods, costs, and safety considerations. The equipment can be installed alone or as part of an overall treatment train, based on site-specific factors. Carbon, in various forms, has been used to adsorb contaminants for some time. The first documented use of carbon as an adsorbent was for medical purposes, in the form of wood char in 1550 B.C. The first documented use for water treatment was in 200 B.C. "to remove disagreeable tastes." In 1785 experimental chemists learned that carbon could accumulate unwanted contaminants from water. Carbon in the activated form was first used as a filter medium in the late 1800s. The understanding of carbon adsorption progressed in the late 19th and early 20th centuries, when vapor phase organic carbon was developed and given its first widespread use as a defense against gas warfare during WWI. The first GAC filters used for water treatment were installed in Europe in 1929. The first GAC filters for water treatment in the United States were installed in Bay City, Michigan, in 1930. In the 1940s, GAC was found to be an efficient purification and separation technology for the synthetic chemical industry. By the late 1960sand early 1970s, GAC was found to be very effective at removing a broad spectrum of synthetic chemicals from water and gases (i.e., from the vapor phase).
