This book was released on 1995 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: LA COMPARAISON DES ISOTHERMES D'ADSORPTION/DESORPTION DE KAU(CN)#2 OBTENUES SUR DIFFERENTS SUPPORTS CARBONES (GRAPHITES, NOIR DE CARBONE, CHARBONS ACTIFS) CARACTERISES EN DETAIL PAR MICROCALORIMETRIE D'IMMERSION, MICROCALORIMETRIE A FLUX DE LIQUIDE, ADSORPTION D'AZOTE A 77 K, ET POROSIMETRIE AU MERCURE MONTRE QUE L'ADSORPTION DES COMPLEXES D'OR SE PRODUIT SOUS FORME D'ESPECES DICYANOAURATES SUR UNE TRES FAIBLE FRACTION DE LA SURFACE TOTALE DU CHARBON ACTIF. L'INEFFICACITE D'UNE GRANDE PARTIE DE LA SURFACE DU CHARBON ACTIF EST DUE D'UNE PART A UNE IMPORTANTE STRUCTURE MICROPOREUSE NON ACCESSIBLE A LA MOLECULE QUI S'ADSORBE ET, D'AUTRE PART A UNE ADSORPTION LOCALISEE SUR UNE PARTIE DES SITES HYDROPHILES DE SURFACE. CETTE ETUDE REVELE AUSSI L'EXISTENCE DE DEUX MECANISMES D'ADSORPTION DANS LE DOMAINE DE CONCENTRATIONS ETUDIE. POUR LES FAIBLES CONCENTRATIONS D'EQUILIBRE, L'ADSORPTION EST COMPLETEMENT IRREVERSIBLE ET GOUVERNEE PAR DES INTERACTIONS ELECTROSTATIQUES ENTRE LES COMPLEXES AUROCYANURE ET DES SITES POLAIRES DE SURFACE CHARGES POSITIVEMENT. DANS CETTE PARTIE INITIALE DE L'ISOTHERME, LE MECANISME D'ADSORPTION EST PRINCIPALEMENT UN MECANISME D'ECHANGE ENTRE LES ANIONS AU(CN)#2 ET DES ANIONS (ENTRE AUTRES CHLORURE) INITIALEMENT PRESENTS A LA SURFACE DU CHARBON ACTIF. PARALLELEMENT A L'ECHANGE D'IONS, DES PROTONS SONT EGALEMENT ADSORBES ET JOUENT UN ROLE DE REGULATION DE LA CHARGE DE SURFACE. LA MESURE DES ENTHALPIES MISES EN JEU AU COURS DU PROCESSUS D'ADSORPTION MONTRE L'EXISTENCE D'UN SECOND TYPE D'INTERACTION -DONNEUR/ACCEPTEUR ENTRE LE COMPLEXE AUROCYANURE ADSORBE ET LA SURFACE DES CHARBONS ACTIFS. CE SECOND TYPE D'INTERACTION POURRAIT ETRE DU A UN TRANSFERT DES ELECTRONS DES CYCLES POLYCONDENSES (DISTORDUS) ADJACENTS AUX SITES ACTIFS CHARGES POSITIVEMENT QUI DONNENT LIEU A L'ECHANGE VERS L'ORBITALE VACANTE DE L'ATOME D'OR DANS LE COMPLEXE ADSORBE. POUR LES SOLUTIONS PLUS CONCENTREES, A PARTIR D'UN CERTAIN TAUX DE RECOUVREMENT, L'ADSORPTION DES COMPLEXES D'OR SUR LE CHARBON ACTIF DEVIENT PARTIELLEMENT REVERSIBLE. LA SEPARATION DE L'ISOTHERME D'ADSORPTION EXPERIMENTALE EN DEUX ISOTHERMES REPRESENTATIVES DES CONTRIBUTIONS IRREVERSIBLES ET REVERSIBLES MONTRE QUE LA REVERSIBILITE SE CARACTERISE PAR UNE PHYSISORPTION SOUS FORME D'ESPECE MOLECULAIRE NEUTRE (KAU(CN)#2) SUR DES PARTIES MOINS REACTIVES DU CHARBON ACTIF. LES RESULTATS OBTENUS PAR MICROCALORIMETRIE CONFIRMENT L'EXISTENCE DE CES DEUX MECANISMES SUCCESSIFS

Download or read book Drinking Water Treatment Chemical and Physical Elimination of Organic Substances and Particles written by Kader Gaid and published by John Wiley & Sons. This book was released on 2023-08-15 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today, hundreds of millions of people drink contaminated water without knowing it. Yet water treatment technologies can effectively eliminate contamination and can supply urban and rural populations with safe drinking water in a secure way. For almost two centuries, the huge number of treatments available to guarantee water quality has grown alongside technological progress, the strengthening of industry norms and the reinforcement of consumer expectations. New treatment methods have been developed according to the advancement of knowledge and new sanitary regulations. This five-volume book sets out to clearly present the variety of treatments available along with their performance, limitations and conditions of use as well as ways to combine them to produce safe drinking water, which is a basic need essential to everyday life. The author shares his expertise acquired at Veolia, a company that is a world leader in water services and sanitation, desalination of sea water and the recycling of wastewater. Founded in France in 1853 to bring safe water to populations and to protect them from waterborne epidemics which ravaged cities, its history is intertwined with that of water treatment.

This book was released on 2012-12-06 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: That residues of pesticide and other "foreign" chemicals in food stuffs are of concern to everyone everywhere is amply attested by the reception accorded previous volumes of "Residue Reviews" and by the gratifying enthusiasm, sincerity, and efforts shown by all the in dividuals from whom manuscripts have been solicited. Despite much propaganda to the contrary, there can never be any serious question that pest-control chemicals and food-additive chemicals are essential to adequate food production, manufacture, marketing, and storage, yet without continuing surveillance and intelligent control some of those that persist in our foodstuffs could at times conceivably endanger the public health. Ensuring safety-in-use of these many chemicals is a dynamic challenge, for established ones are continually being dis placed by newly developed ones more acceptable to food tech nologists, pharmacologists, toxicologists, and changing pest-control requirements in progressive food-producing economies. These matters are of genuine concern to increasing numbers of governmental agencies and legislative bodies around the world, for some of these chemicals have resulted in a few mishaps from improper use. Adequate safety-in-use evaluations of any of these chemicals per sisting into our foodstuffs are not simple matters, and they incorporate the considered judgments of many individuals highly trained in a variety of complex biological, chemical, food technological, medical, pharmacological, and toxicological disciplines.
