KUNTZ and published by . This book was released on 1995 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: AVEC LA RECENTE LOI SUR L'EAU DE JANVIER 1992 QUI COMPORTE UNE NECESSITE DE TRAITEMENTS DES EAUX RESIDUAIRES TOUJOURS PLUS POUSSES, DONC DELICATS A GERER, IL DEVIENT INDISPENSABLE D'ACCEDER A UNE MEILLEURE CONNAISSANCE DES FLUX DE POLLUTION, NOTAMMENT AZOTEE. OR, LA MESURE EN CONTINU ET SUR SITE DES NITRATES (NO 3) N'EST PAS ENCORE SUFFISAMMENT FIABLE OU EST TROP COMPLEXE ET COUTEUSE. POUR TENTER DE REMEDIER A CETTE SITUATION, NOUS AVONS ETUDIE UN PRINCIPE DE MESURE SIMPLE ET RELATIVEMENT SELECTIF : L'ABSORPTION DIRECTE DU RAYONNEMENT ULTRAVIOLET PAR LES IONS NITRATES. UNE ETUDE DE FAISABILITE AVEC UN SPECTROPHOTOMETRE DE LABORATOIRE, SUR DES ECHANTILLONS REELS, NOUS A PERMIS D'OBTENIR UN MODELE SIMPLE DE CALCUL DES CONCENTRATIONS EN NITRATES, APPLICABLE AUX EAUX USEES DE REJET PROVENANT DE DIFFERENTS TYPES DE TRAITEMENTS, MAIS AUSSI A DES EAUX SUPERFICIELLES OU DE NAPPE. CE MODELE UNIVERSEL (INDEPENDANT DU SITE) TIENT COMPTE DE CERTAINS INTERFERENTS DANS DES GAMMES DE CONCENTRATIONS SUSCEPTIBLES D'Y ETRE RENCONTREES. LA MESURE DES MATIERES EN SUSPENSION ET DES MATIERES ORGANIQUES A ETE PRISE EN COMPTE, RENDANT POSSIBLE LA REALISATION D'UN CAPTEUR MULTIPARAMETRE. LA LONGUEUR DU TRAJET OPTIQUE RETENUE PERMET D'OBTENIR UNE BONNE LINEARITE SUR LA GAMME 0-150 MG/L NO 3 ET UNE PRECISION SUR EFFLUENTS TRAITES DE L'ORDRE DE 3 MG/L (NIVEAU DE CONFIANCE A 95%). D'AUTRE PART, AUCUNE FILTRATION DE L'EFFLUENT N'EST NECESSAIRE POUR DES CONCENTRATIONS EN MATIERES EN SUSPENSION ALLANT JUSQU'A 300 MG/L, ET UN SYSTEME DE NETTOYAGE PAR RACLAGE DEVRAIT ETRE ADAPTABLE AUX DIMENSIONS DE LA CELLULE DE MESURE. CETTE ETUDE S'EST POURSUIVIE PAR LA REALISATION D'UNE MAQUETTE, PREFIGURANT UN PROTOTYPE POUR SA PARTIE OPTIQUE : SOURCE DEUTERIUM, FIBRES OPTIQUES ET SPECTROPHOTOMETRE MONOLITHIQUE A BARRETTE DE PHOTODIODES. LES PREMIERS RESULTATS SONT TRES ENCOURAGEANTS PUISQU'ILS CONFIRMENT LA FAISABILITE DE LA MESURE DES NITRATES, MAIS AUSSI DE L'UTILISATION DES FIBRES OPTIQUES. CE DERNIER POINT N'EST RENDU POSSIBLE QUE PAR L'EMPLOI DE LONGUEURS D'ONDE SUPERIEURES A 220 NM, LIMITE DE LEUR TRANSMISSION DANS L'ULTRAVIOLET.

Download or read book Nouvelles techniques analytiques spectrométriques et traitement de polluants spécifiques présents dans l'environnement written by and published by . This book was released on 2000 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce travail porte sur l'instrumentation, l'analyse en ligne, et le traitement des eaux chargées en polluants organiques. Il se subdivise en deux parties ; l'une relative au développement et à l'application d'instruments de mesure optiques originaux pour la détermination de traces de polluants organiques et minéraux, l'autre correspond à̧ l'évaluation d'une nouvelle méthode de traitement des pesticides en utilisant les propriétés redox du fer zéro-valent. Suite aux progrès réalisés dans les domaines des détecteurs optiques et dans celui de la miniaturisation des monochromateurs, la première partie fait le point sur l'état de l'art de la spectrométrie d'émission pour la mesure en ligne des traces de composés organiques. Les possibilités offertes par la phosphorimétrie à température ambiante et la développement d'un appareil de mesure portable équipé de fibres optiques bifurquées et d'un détecteur multicanal, ont permis la détection et la mesure de traces d'hydrocarbures aromatiques polycycliques et de pesticides présents dans les eaux. ... L'ensemble des résultats obtenus ouvre des perspectives sur la miniaturisation des systèmes optroniques avec la possibilité de générer de véritables capteurs intelligents et sur la chimie sèche pour laquelle nous proposons des nouvelles techniques de fonctionnalisation des surfaces sensibles par des réactifs micro-encapsulés. La validation des procédés de traitement des eaux chargées en nitrates ou en pesticides par le fer zéro-valent ouvre une nouvelle alternative au traitement des effluents agricoles ou industriels. Le couplage de ces nouveaux procédés de dépollution avec les analyseurs en ligne devrait conduire, dans un proche avenir, à de nouveaux procédés de traitement et de contrôle des effluents pollués.

Download or read book Wood Adhesives written by Antonio Pizzi and published by CRC Press. This book was released on 2011-01-07 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood adhesives are of tremendous industrial importance, as more than two-thirds of wood products in the world today are completely or partially bonded together using a variety of adhesives. Adhesive bonding offers many advantages over other joining methods for wood components, and there has been a great deal of R& D activity in devising new wood adhesives or improving the existing ones. The modern mantra in all industrial sectors is: "think green, go green," which has attracted much attention in the wood adhesive industry. Therefore, there is also a lot of research activity in synthesizing environmentally benign and human-friendly wood adhesives. This book is divided into four parts: Part 1: Fundamental Adhesion Aspects in Wood Bonding; Part 2: Synthetic Adhesives; Part 3: Environment-friendly adhesives; and Part 4: Wood Welding and General Paper. It addresses many different types of wood adhesives, as well as bonding (welding) of wood components without adhesives, a more recent development. The information contained in this book is valuable for individuals engaged in all aspects of wood adhesion and adhesives and, hopefully, will inspire new ideas in wood adhesives, a topic of vital industrial importance.
