Abstract:
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.

Claim (Index 17):
A method for producing a composition comprising modified, chromate-deficient red mud with a mineral composition of 10 to 50% by weight of iron compounds, 12 to 35% by weight of aluminium compounds, 5 to 17% by weight of silicon compounds, 2 to 10% by weight of titanium dioxide, 0.5 to 6% by weight of calcium compounds, and 0 to 1 ppm of chromium (VI) compunds, wherein the method comprises the following steps:\n a) providing neutralised red mud, b) adding a poorly soluble reducing agent for Cr(VI) to the red mud and mixing of the poorly soluble reducing agent for Cr(VI) with the red mud, c) reducing chromium(VI) compounds contained in the red mud by means of the poorly soluble reducing agent for Cr(VI) to chromium(III) compounds in aqueous systems producing a modified, chromate-deficient red mud, and d) adding a pH buffer system which is configured for stabilising a pH range in which the poorly soluble reducing agent for Cr(VI) and the resulting Cr(III) has a solubility in water at 25\u00b0 C. of less than 1 g/l.
