Abstract[English]
A method for quantifying natural fibers and/or chemical fibers present in a liquid effluent from a textile treatment device. A sample of the liquid effluent or its filtration residue is heated in an inert atmosphere between an initial temperature (TO) of at most 290°C and a final temperature (TF) of at least 550°C, and a curve of the evolution, as a function of the temperature, of a representative amount of hydrocarbon compounds released by the sample is measured. From predefined initial, intermediate (Tl) and final integration temperatures of said curve, an amount of hydrocarbon compounds released by the natural fibers of the sample and/or an amount of hydrocarbon compounds released by the chemical fibers of the sample is determined. Then, on the basis of predetermined laws of correlation, a mass percentage of natural fibers and/or chemical fibers present in the sample is deduced therefrom.[French]
Procédé pour quantifier des fibres naturelles et/ou des fibres chimiques présentes dans un effluent liquide issu d'un dispositif de traitement de textiles. On chauffe en atmosphère inerte un échantillon de l'effluent liquide ou de son résidu de filtration entre une température initiale (TO) valant au plus 290°C et une température finale (TF) valant au moins 550°C, et on mesure une courbe de l'évolution en fonction de la température d'une quantité représentative de composés hydrocarbonés libérés par l'échantillon. A partir de températures prédéfinies d'intégration initiale, intermédiaire (Tl) et finale de ladite courbe, on détermine une quantité de composés hydrocarbonés libérés par les fibres naturelles de l'échantillon et/ou une quantité de composés hydrocarbonés libérés par les fibres chimiques de l'échantillon. Puis, à partir de lois de correspondance prédéterminées, on en déduit un pourcentage massique de fibres naturelles et/ou de fibres chimiques présentes dans l'échantillon.
