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 19):
The method according to  claim 17  further comprising the following steps:\n a) providing neutralised red mud, \n b) reducing iron(III) compounds contained in the red mud to iron(II) compounds and reducing chromium(VI) compounds contained in the red mud to chromium(III) compounds in aqueous systems, \n c) adding a carbonate compound to the solution obtained in step b) to form iron(ll) carbonate, and \n 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.
