Abstract

L'INVENTION CONCERNE UN PROCÉDÉ DE TRAITEMENT D'EAU CONTENANT DES POLLUANTS ORGANIQUES (COLORANTS ET PESTICIDES), NOTAMMENT EN VUE DE SA RÉUTILISATION POUR L'IRRIGATION, DANS L'INDUSTRIE OU VOIR MÊME EN TANT QU'EAU POTABLE. CE PROCÉDÉ EST ÉGALEMENT APPLICABLE AU TRAITEMENT D'EFFLUENTS INDUSTRIELS RICHES PAR DES IMPURETÉS ORGANIQUES.LE PROCÉDÉ DÉVELOPPÉ CONCERNE L'UTILISATION DES PHOTO-CATALYSEURS À BASE DES CARBONES NANOSTRUCTURÉS ET UN OXYDE MÉTALLIQUE DE TAILLE NANOSCOPIQUE. LES VERROUS SCIENTIFIQUES ET TECHNOLOGIQUES DE CE PROCÉDÉ RÉSIDENT EN FAITE DANS LA PRÉPARATION DES NANOCOMPOSITES À BASE DE GRAPHITE ET GRAPHÈNE (OXYDE DE GRAPHITE, GRAPHÈNE, NANOCOMPOSITE GRAPHÈNE - DIOXYDE DE TITANE) CAPABLES DE DÉGRADER LES POLLUANTS ORGANIQUES DANS L'EAU EN ABSENCE DES IRRADIATIONS AUX ULTRA-VIOLETS (UV), DE MÊME QUE LEURS PROCÉDÉS DE FABRICATION ET LEURS UTILISATIONS.The invention relates to a method for treating water containing organic pollutants (dyes and pesticides), especially for its reuse for irrigation, in the industry or even to be used as drinking water. This method is also applicable to the treatment of industrial effluents rich in organic impurities. THE SCIENTIFIC AND TECHNOLOGICAL LATCHES OF THIS PROCESS RESULT IN THE PREPARATION OF NANOCOMPOSITES BASED ON GRAPHITE AND GRAPHENE (GRAPHITE OXIDE, GRAPHENE, GRAPHENE NANOCOMPOSITE - TITANIUM DIOXIDE) CAPABLE OF DEGRADING ORGANIC POLLUTANTS IN WATER IN ABSENCE OF IRRADIATION ULTRA VIOLETS (UV), AS WELL AS THEIR MANUFACTURING PROCESSES AND USES THEREOF.
