IRON OXIDE REMOVAL FROM SOILS AND CLAYS BY A

2013-1-1  IRON OXIDE REMOVAL FROM SOILS AND CLAYS BY A DITHIONITE-CITRATE SYSTEM BUFFERED WITH SODIUM BICARBONATE by 0. P. MEHBA AND M. L. JACKSON Department of Soils, University of Wisconsin, Madison, Wisconsin ABSTRACT The oxidation potential of dithionite (Na2S2Ü4) increases from 0.37 V to 0.73 V with increase in p H from 6 to 9, because hydroxyl is consumed during oxidation of dithionite.

The removal of iron oxide from clay by sodium dithionite

On the removal of iron oxide from clays with sodium dithionite-sulfuric acid solution (pH2-3), the reducing agent is used not only for the reductio n of Fe 3+ to Fe 2+ but for the reaction with atmospheric oxygen and the self-decomposition reaction, therefore it is necessary to determine effective conditions of the reduci ng reaction.

Biological beneficiation of kaolin: A review on iron removal

2015-4-1  Iron oxide/hydroxides may be eliminated from kaolinite clays by dissimilatory Fe III reduction. Bacterial Fe III reduction has been recognized as a significant process which catalyzed many natural and contaminant biogeochemical cycles (Kostka et al., 2002).In this process, microorganisms reduce Fe III, even in the structural form, for purposes other than assimilation of iron (Kostka et al

Effect of organic acids on ferric iron removal from iron

2000-3-1  The results of the organic acid treatments are shown in Table 2.The deferration effect of formic, acetic, succinic, citric and tartaric acids was lower than that of equimolar (0.15 M) solutions of l-ascorbic and oxalic acids under the same experimental conditions.The brightness of the clay was increased from 66.33 (raw clay) to 76.85 and 81.85% for l-ascorbic- and oxalic acid-treated clays

Iron Oxide Removal from Soils and Clays by a Dithionite

The oxidation potential of dithionite (Na2S2O4) increases from 0.37 V to 0.73 V with increase in pH from 6 to 9, because hydroxyl is consumed during oxidation of dithionite. At the same time the amount of iron oxide dissolved in 15 minutes falls off (from 100 percent to less than 1 percent extracted) with increase in pH from 6 to 12 owing to solubility product relationships of iron oxides.
