Removal of Iron Oxide Fine Particles from Waste Water

Although the suspended iron oxide particles were hardly removed from suspension using other aerators such as a single orifice and a glass ball filter, the microbubble generator achieved 90% recovery of the particles in 60 minutes. In bulk liquid, both surfaces of microbubbles and iron oxide particles became electrically charged.

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.

Removal and Oxidation of As(III) from Water Using Iron Oxide

Iron oxides such as magnetite and maghemite coated with cetyltrimethylammonium bromide (CTAB) are very promising materials for wastewater treatment because iron oxide can be easily separated from solutions using the magnetic separation procedure Iron oxide (IO) coated CTAB was synthesized by an adapted co-precipitation method. In the present study, the IO-CTAB was used for removing arsenic

Acidic Cleaning And Oxide Removal

Magnetic iron oxide is attacked least by sulfuric acid and, reportedly, is removed only after reduction by the hydrogen released during reaction of steel and acid. Moreover, the ferric oxide of mill scale differs from that in rust; the latter is more easily removed by acid when not excessively dehydrated.
