Book excerpt: L'evolution constante des normes de qualite de l'eau et les nouvelles pratiques industrielles impliquent le developpement de procedures simples et rapides, adaptees aux techniques d'analyse en continu. Les metaux presentent, parmi les nombreux polluants rejetes dans le milieu naturel, un risque sanitaire important et leur concentration doit etre controlee frequemment dans les eaux naturelles et les effluents, sur site, afin de permettre une prise de decision rapide en cas de pollution accidentelle. Cependant, les methodes usuelles pour l'analyse des metaux sont couteuses et complexes, et ne permettent pas leur determination sur site. L'objectif de cette etude est donc de developper une procedure analytique simple et rapide pour l'analyse de 6 metaux (cu, fe, hg, ni, pb, zn) dans les eaux, adaptable a un analyseur en continu, par l'utilisation d'une separation complexometrique couplee a une detection u.v. Visible robuste, apres une etape rapide de photo-oxydation des echantillons. Dans un premier temps, differents reactifs ont ete elabores pour etre specifiques aux elements metalliques etudies. Pour chaque reactif, chaque complexe metallique forme presente une absorptivite differente des autres complexes et des ligands sous forme libre, permettant ainsi la differenciation des differents complexes metalliques et la quantification des metaux etudies par l'utilisation d'un calcul de deconvolution spectrale, realise sur des fenetres de longueurs d'onde dependant des metaux etudies et des reactifs utilises. La procedure proposee montre des resultats satisfaisants en comparaison avec la methode de reference d'analyse des metaux, et permet la determination quasi-simultanee de 6 metaux dans les eaux naturelles et les effluents industriels.

This book was released on 1993 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: LA MESURE SIMPLE DE LA CONCENTRATION DES METAUX DANS LES EAUX ET LES EFFLUENTS N'EST PAS FACILE, CAR LES METHODES SONT SOUVENT COMPLEXES ET COUTEUSES, OU NECESSITANT UN TEMPS OPERATOIRE IMPORTANT. NOUS PROPOSONS UNE NOUVELLE METHODE POUR LA DETERMINATION DU CUIVRE, DU FER, DU MERCURE ET DU CADMIUM DANS LES EAUX ET/OU LES EFFLUENTS. LA METHODE EST BASEE SUR UNE MESURE SPECTROPHOTOMETRIQUE INDIRECTE APRES UNE REACTION TRES RAPIDE DUE A L'EMPLOI D'UN SEUL REACTIF. LE MEME REACTIF EST EMPLOYE POUR LA DETERMINATION SIMULTANEE DU CUIVRE ET DU FER, MAIS DES REACTIFS, SPECIFIQUES SONT UTILISES POUR LE MERCURE ET LE CADMIUM. LA COMPOSITION GENERALE DE CES REACTIFS CONSISTE EN UN MELANGE DE LIGANDS (UN AGENT CHELATANT POUR LE METAL, LES AUTRES SERVANT D'AGENTS MASQUANTS POUR LES IONS INTERFERENTS) D'ALCOOL ETHYLIQUE ET D'AUTRES COMPOSES POUR TAMPONNER LE PH. LA PROCEDURE ANALYTIQUE EST TRES SIMPLE CAR LE REACTIF EST DIRECTEMENT AJOUTE A L'ECHANTILLON (1/5 V/V) ET LE SPECTRE EST INSTANTANEMENT ACQUIS POUR LE CALCUL DE LA CONCENTRATION. LES CARACTERISTIQUES DES METHODES SONT PROCHES DE CELLES OBTENUES PAR SPECTROMETRIE D'ABSORPTION ATOMIQUE. LES RESULTATS DE LA COMPARAISON ENTRE CES METHODES ET DES ANALYSES DE REFERENCES MONTRENT UNE BONNE CORRELATION POUR LES DIFFERENTS ECHANTILLONS TESTES. UN GRAND NOMBRE D'INTERFERENCES EST ELIMINE, EXCEPTE LORS DE LA MESURE DU FER DANS LES EAUX NATURELLES PRESENTANT UNE IMPORTANTE CONCENTRATION EN SUBSTANCES HUMIQUES: CES DERNIERES POSSEDENT DES COMPLEXES PLUS STABLES QUE CEUX FORMES AVEC LE REACTIF SPECIFIQUE. NEANMOINS, CES METHODES CONVIENNENT PARFAITEMENT POUR LA MESURE EN CONTINU, COMPTE TENU DE LA FACILITE D'EXECUTION ET DU FAIBLE COUT DE L'EQUIPEMENT REQUIS
Book Synopsis Faecal Sludge Management by : Linda Strande
Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.

Book Synopsis Adhesion between polymers and concrete / Adhésion entre polymères et béton by : H. R. Sasse
Download or read book Adhesion between polymers and concrete / Adhésion entre polymères et béton written by H. R. Sasse and published by Springer. This book was released on 2013-11-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preface Adhesion is a phenomenon architects and civil engineers are not very familiar with. In other disciplines knowledge about surface properties and the background of bonding energies is also far from satisfactory; nevertheless there are many important· applications in concrete engineering, where adhesion is necessary for success and durability. These include: - coating and painting - repair of concrete surfaces - bonding of fresh to old concrete - crack injection - glueing of precast elements - glueing of steel to concrete, etc. In 1981 RILEM established the technical committee 52-RAC 'Resin Adherence to Concrete'. The main aims of the committee's work were - to collect research results and practical experiences - to initiate and coordinate research programs - to develop, on a scientific base, test methods for field and for laboratory purposes. One of the results of the committee's work is a state-of-the-art report, which will be presented orally as a General Report at the International Symposium ISAP '86, and will be printed either in the RILEM journal Materials and Structures or separately. Several test recommendations have been elaborated and will be prepared as drafts for the participants ofISAP '86. These are: - direct tensile test - pull-off test - direct shear test - slant shear test - four-point bending test - dynamic loading test - thermal compatibility test (two versions) - injectibility test.

Available in PDF, EPUB and Kindle. Book excerpt: Techniques of performing applied mineralogy investigations, and applications and capabilities of recently developed instruments for measuring mineral properties are explored in this book intended for practicing applied mineralogists, students in mineralogy and metallurgy, and mineral processing engineers. The benefits of applied mineralogy are presented by using in-depth applied mineralogy studies on base metal ores, gold ores, porphyry copper ores, iron ores and industrial minerals as examples. The chapter on base metal ores includes a discussion on the effects of liberation, particle sizes and surfaces coatings of Pb, Cu, Fe, Ca and So4- on the recoveries of sphalerite, galena and chalcopyrite. The chapter on gold discusses various methods of determining the quantities of gold in different minerals, including 'invisible' gold in pyrite and arsenopyrite, so that a balance of the distribution of gold among the minerals can be calculated. This book also discusses the roles of pyrite, oxygen, moisture and bacterial (thiobacillus ferrooxidans) on reactions that produce acidic drainage from tailings piles, and summarizes currently used and proposed methods of remediation of acidic drainage.

Download or read book Nanomaterials For Energy Conversion And Storage written by Dunwei Wang and published by World Scientific. This book was released on 2017-11-10 with total page 836 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of nanomaterials in energy conversion and storage represents an opportunity to improve the performance, density and ease of transportation in renewable resources. This book looks at the most recent research on the topic, with particular focus on artificial photosynthesis and lithium-ion batteries as the most promising technologies to date. Research on the broad subject of energy conversion and storage calls for expertise from a wide range of backgrounds, from the most fundamental perspectives of the key catalytic processes at the molecular level to device scale engineering and optimization. Although the nature of the processes dictates that electrochemistry is a primary characterization tool, due attention is given to advanced techniques such as synchrotron studies in operando. These studies look at the gap between the performance of current technology and what is needed for the future, for example how to improve on the lithium-ion battery and to go beyond its capabilities.Suitable for students and practitioners in the chemical, electrochemical, and environmental sciences, Nanomaterials for Energy Conversion and Storage provides the information needed to find scalable, economically viable and safe solutions for sustainable energy.

This book was released on 2014-03-15 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a practical handbook providing a step-by-step approach to the techniques used for characterizing wastewater sources and investigating sites where collection, treatment and reuse/disposal technologies will be installed. It is intended to help enable local implementation of on-site and decentralized wastewater management system (DWMS)for wide scale use in development settings. How to Design Wastewater Systems for Local Conditions in Developing Countries helps local service providers and regulatory officials make informed decisions through the use of tools, checklists and case studies. It includes a link to a web based community of on-site and decentralized wastewater professionals, which contains related tools and case studies. This handbook serves as a reference for training classes, certification programs, and higher education programs in civil and sanitary engineering. There is an increasing interest on the part of local government officials and private sector service providers to implement wastewater treatment systems to solve sanitation problems. The model presented in this handbook promotes activities that first generate data related to source and site conditions that represent critical inputs, and then applies this information to the technology selection process. Matching the most appropriate technologies to the specific needs of the wastewater project is the key that leads to long term sustainability. How to Design Wastewater Systems for Local Conditions in Developing Countries is an invaluable resource for public sector decision makers and private sector service providers in developing countries. It is also a useful text for students at engineering colleges in developing countries interested in taking a class that teaches the methods of decentralized wastewater management system (DWMS) development.

Book Synopsis An Introduction to Differential Manifolds by : Jacques Lafontaine
Download or read book An Introduction to Differential Manifolds written by Jacques Lafontaine and published by Springer. This book was released on 2015-07-29 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an introduction to differential manifolds. It gives solid preliminaries for more advanced topics: Riemannian manifolds, differential topology, Lie theory. It presupposes little background: the reader is only expected to master basic differential calculus, and a little point-set topology. The book covers the main topics of differential geometry: manifolds, tangent space, vector fields, differential forms, Lie groups, and a few more sophisticated topics such as de Rham cohomology, degree theory and the Gauss-Bonnet theorem for surfaces. Its ambition is to give solid foundations. In particular, the introduction of “abstract” notions such as manifolds or differential forms is motivated via questions and examples from mathematics or theoretical physics. More than 150 exercises, some of them easy and classical, some others more sophisticated, will help the beginner as well as the more expert reader. Solutions are provided for most of them. The book should be of interest to various readers: undergraduate and graduate students for a first contact to differential manifolds, mathematicians from other fields and physicists who wish to acquire some feeling about this beautiful theory. The original French text Introduction aux variétés différentielles has been a best-seller in its category in France for many years. Jacques Lafontaine was successively assistant Professor at Paris Diderot University and Professor at the University of Montpellier, where he is presently emeritus. His main research interests are Riemannian and pseudo-Riemannian geometry, including some aspects of mathematical relativity. Besides his personal research articles, he was involved in several textbooks and research monographs.
