Available in PDF, EPUB and Kindle. Book excerpt: L'OZONE TROPOSPHERIQUE EST PRODUIT A GRANDE ECHELLE LORS DES CHAINES D'OXYDATION PHOTOCHIMIQUE DES POLLUANTS, CATALYSEES PAR LES OXYDES D'AZOTE NOX, NOY. L'ANALYSEUR AUTOMATIQUE REALISE (SENSIBILITE 10 PPT NO) PERMET LEUR MESURE EN ZONE NON DIRECTEMENT POLLUEE UV ET LES NOY PAR REDUCTION CATALYTIQUE. L'ANALYSE DE MESSES D'AIR CONTINENTALES EN BRETAGNE EN JUIN 1989 A MONTRE UNE PRODUCTION D'OZONE A GRANDE ECHELLE (60-65 PPB 03, 1-4 PPB NOX) ET UNE PRODUCTION LOCALE (100 PPB 03, 5-10 PPB NOX). LES ETUDES DANS LA TROPOSPHERE LIBRE (OBSERVATOIRE DU PIC DU MIDI) ONT MONTRE UNE FAIBLE PHOTOCHIMIE POUR LES MASSES D'AIR OCEANIQUES EN HIVER (45 PPB 03, 400 PPT NOY, NOX/NOY=0.30-0.35), BIEN PLUS IMPORTANTE POUR LES MASSES D'AIR CONTINENTALES EN MAI (60-65 PPB 03, 3-4 PPB NOY, NOX/NOY=0.05-0.1). LES MESURES D'OZONE AU PIC DU MIDI DURANT LA PERIODE 1886-1909, ASSOCIEES AUX MESURES RECENTES EN 1982-1991, ONT PERMIS DE RETRACER L'EVOLUTION DE L'OZONE TROPOSPHERIQUE, AVEC UN TAUX D'ACCROISSEMENT ANNUEL DE 1.6% DANS L'HEMISPHERE NORD

Download or read book ETUDE ET MISE AU POINT D UN PROCEDE DE PRODUCTION D OXYDES D AZOTE PAR REDUCTION ELECTROCHIMIQUE DE L ACIDE NITRIQUE POUR LE RETRAITEMENT DES COMBUSTIBLES IRRADIES written by PHILIPPE.. VIERS and published by . This book was released on 1990 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: CETTE ETUDE PRESENTE UNE ALTERNATIVE AU PROCEDE CHIMIQUE DE PRODUCTION D'OXYDES D'AZOTE, EMPLOYES COMME AGENTS D'OXYDATION, LORS DU RETRAITEMENT DES COMBUSTIBLES IRRADIES. LA VOIE ELECTROCHIMIQUE PROPOSEE QUI CONSISTE A PRODUIRE CES OXYDES PAR ELECTRO-REDUCTION DE L'ACIDE NITRIQUE, ECARTE LES PROBLEMES ACTUELS POSES PAR L'APPORT D'UN CATION ETRANGER. UNE REVUE BIBLIOGRAPHIQUE PRESENTE LES DIFFERENTS EQUILIBRES RENCONTRES AUSSI BIEN EN PHASE GAZEUSE QU'EN SOLUTION DANS LE SYSTEME HNO#3-H#2O-OXYDES D'AZOTE. LES DIFFERENTS COMPOSES SUSCEPTIBLES D'ETRE OBTENUS PAR ELECTRO-REDUCTION DE L'ACIDE NITRIQUE SONT PRESENTES. LE PROBLEME POSE EST CELUI DE LA SELECTIVITE DE L'OPERATION ET DE LA DEFINITION DU MELANGE D'OXYDES OBTENU. APRES AVOIR CHOISI DEUX METAUX SUSCEPTIBLES DE CONVENIR (TANTALE ET TITANE) ET EFFECTUE UNE ETUDE VOLTAMPEROMETRIQUE CLASSIQUE SUR CEUX-CI, LE PROBLEME A ETE ENVISAGE DANS SA GLOBALITE. L'ETUDE EST EFFECTUEE DANS UNE CELLULE A COMPARTIMENTS ELECTROLYTIQUE ET GAZEUX SEPARES, LES OPERATIONS D'ELECTROLYSE ET DE DEGAZAGE ETANT CONDUITES CONJOINTEMENT. LA POSSIBILITE DE PRODUIRE CES OXYDES AVEC UN RENDEMENT EN COURANT VOISIN DE 100% A ETE DEMONTRE SUR CATHODE DE TANTALE ET DE TITANE. TOUTEFOIS, CE DERNIER METAL SE MONTRE PLUS FAVORABLE PAR L'ABSENCE DE TRACE DE SOUS-PRODUITS (HYDROGENE, AMMONIUM), DANS LES CONDITIONS OPERATOIRES SUIVANTES: CONCENTRATION EN HNO#3 SUPERIEURE A 8 MOL/L, DENSITE DE COURANT D'ENVIRON 150 MA/CM#2, TEMPERATURE COMPRISE ENTRE 25 ET 45C. LA COMPOSITION DU MELANGE D'OXYDES PRODUIT, EST DANS CES CONDITIONS, FIXEE PAR LA CONCENTRATION DE L'ACIDE NITRIQUE

This book is divided into four clearly defined parts: measuring organic indoor pollutants, investigation concepts and quality guidelines, field studies, and emission studies. The authors cover physico-chemical fundamentals of organic pollutants, relevant definitions and terminology, emission sources, sampling techniques and instrumentation, exposure assessment as well as methods for control. Test methods and studies for various indoor environments are described, such as automobile interiors, museum environments, or rooms with air ventilation. Emission sources covered include household and consumer products as well as electronic devices and office equipment. The book is aimed at chemists, physicists, biologists, and medical doctors at universities and research facilities, in industry and environmental laboratories as well as regulative bodies.
