Catalytic Elimination of Phenol, Organic Pollutant, From Industrial Wastewater on Fe-Zsm-5 Zeolites

Abstract

two series of zeolites,ferrisilicates (based on salts of Fe3+) and ferrocilicates (based on salts of Fe2+)where prepared by hydrothermal synthesi s involving direct mi neralizing action of met hylamine (MA) to introduce the iron ismorphic position .these solids were char acterized by various physocochemi cal techniques (XRD,SEM,BE T and chemi cal analysis by atomic absorption(AA)... depister les situations solicitantes de troubles musculo-squelettique chez les sages femmes au travail et au rechercher les causes de ces sollicitations *proposer des recommandations afin de reduire les facteurs de risques de trouble musculo-squelletiques
