Title (EN) METHOD FOR TREATING AQUEOUS MATRICES
(FR) PROCÉDÉ DE TRAITEMENT DE MATRICES AQUEUSES
(ES) PROCESO DE TRATAMIENTO DE MATRICES ACUOSAS
Abstract:
(EN) The invention relates to a method for the breaking down and/or removal of contaminants present in aqueous matrices, using a material made of fibres doped with metal or metal oxide nanoparticles. The method involves a first step of acidification and adding oxidising agents to promote the reaction of the aqueous matrix with the doped fibre material. The method according to the invention permits the significant reduction of the load of contaminants present in the aqueous matrices originating from domestic and industrial activities.
(FR) L’invention concerne un procédé pour la dégradation et/ou l’élimination de contaminants présents dans des matrices aqueuses, qui utilise une matière à base de fibres dopées de nanoparticules métalliques ou d’oxydes métalliques. Le procédé prévoit une étape initiale d’acidification et d’ajout d’agents oxydants pour favoriser la réaction de la matrice aqueuse avec la matière à base de fibres dopées. Le procédé de l’invention permet de réduire considérablement la charge de contaminants présents dans des matrices aqueuses provenant d’activités domestiques et industrielles.
