This item is printed on demand - Print on Demand Titel. Neuware -La cendre de balle de riz est une bonne source de silice. La teneur en silice de la RHA est de près de 95 %. La silice est utilisée comme matière première pour la fabrication du verre, du caoutchouc, etc. La cendre de balle de riz est utilisée pour l'extraction de la silice car elle est économiquement viable par rapport à d'autres sources. Dans la présente étude, la silice est extraite de la cendre de balle de riz en utilisant de l'hydroxyde de sodium et du HCl conc. comme solvants à différentes températures (°c), temps (hr), concentration (N) respectivement. Un rendement maximum de 95% a été obtenu à partir de RHA à une température de 100°C, un temps de 2 heures et une concentration de 2N par traitement acide. Un rendement minimum de 41% a été obtenu à partir de RHA à une température de 100 ºc, une durée de 1 heure et une concentration de 2N. La silice obtenue a fait l'objet d'une analyse qualitative FTIR. La comparaison du rendement obtenu à partir de l'extraction en utilisant de l'hydroxyde de sodium et de l'HCl conc. comme solvants est faite.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 52 pp. Französisch.…
