Abstract:
(EN) The invention relates to a composition which contains modified chromate-deficient red mud, comprising a mineral composition of - 10 to 50 wt.% of iron compounds, - 12 to 35 wt.% of aluminum compounds, - 5 to 17 wt.% of silicon compounds, - 2 to 10 wt.% of titanium dioxide, - 0.5 to 6 wt.% of calcium compounds, - 0 to 1 ppm of chromium (VI) compounds, and - optionally additional unavoidable impurities. The composition, in particular the modified chromate-deficient red mud, contains a poorly soluble reducing agent for Cr(VI). In this manner, an inexpensive chemical composition is provided in particular as an iteratively functioning long-term adsorbent for pollutants in liquid, gaseous, and solid milieu. The invention further relates to a method for producing same and to uses thereof.
(FR) La présente invention concerne une composition, contenant une boue rouge pauvre en chromate et modifiée, comprenant un composition minérale de - 10 à 50 pourcents en poids de composés du fer, - 12 à 35 pourcents en poids de composés d'aluminium, - 5 à 17 pourcents en poids de composés de silicium, - 2 à 10 pourcents en poids d'oxyde de titane, - 0,5 à 6 pourcents en poids de composés de calcium, - 0 à 1 ppm de composés du chrome (VI) et - éventuellement d'autres impuretés inévitables; la composition, notamment de la boue rouge pauvre en chromate et modifiée, contenant un agent réducteur de Cr(VI), difficilement soluble. Cela permet d'obtenir, en particulier, une composition chimique peu coûteuse en tant qu'absorbant long terme à action itérative pour des substances toxiques dans un milieu liquide, gazeux et solide. L'invention concerne également un procédé de fabrication et leurs utilisations.
(DE) Die vorliegende Erfindung betrifft eine Zusammensetzung, enthaltend modifizierten, chromatarmen Rotschlamm mit einer mineralischen Zusammensetzung von - 10 bis 50 Gewichtsprozent Eisenverbindungen, - 12 bis 35 Gewichtsprozent Aluminiumverbindungen, - 5 bis 17 Gewichtsprozent Siliziumverbindungen, - 2 bis 10 Gewichtsprozent Titandioxid, - 0,5 bis 6 Gewichtsprozent Calciumverbindungen, - 0 bis 1 ppm an Chrom(VI)-Verbindungen und - gegebenenfalls weitere unvermeidbare Verunreinigungen, wobei die Zusammensetzung, insbesondere der modifizierte, chromatarme Rotschlamm, ein schwerlösliches Reduktionsmittel für Cr(VI) enthält. Hierdurch wird insbesondere eine kostengünstige chemische Zusammensetzung als iterativ wirkendes Langzeit- Adsorbens für Schadstoffe in flüssigem, gasförmigem und festem Milieu bereitgestellt. Ferner wird ein Verfahren zu deren Herstellung und Verwendungen angegeben.
