IRON OXIDE REMOVAL FROM SOILS AND CLAYS BY A DITHIONITE ...

Jan 01, 2013  It was found that the bicarbonate-buffered Na 2 S 2 O 4-citrate system was the most effective in removal of free iron oxides from latosolic soils, and the least destructive of iron silicate clays as indicated by least loss in cation exchange capacity after the iron oxide removal treatment. With soils the decrease was very little but with the very susceptible Woody district nontronite, the decrease was

Sorption of Heavy Metals on Clay Minerals and Oxides: A ...

Feb 28, 2018  Sorption of heavy metals plays a vital role in controlling environmental pollution. Here, we reviewed the sorption of heavy metals such as Ni, Co, Cu, Zn, V, Pb, Hg, In, As, Cd, Cr, Ga, Cs, Mn, V, Eu, Mo, Th, TI and Cr on metal oxides and clay minerals. The mechanism of association between these ions and the host minerals, and the factors controlling their sorption are discussed in detail.

How to Clean Brick Concrete and Remove Red Clay Stains

Feb 05, 2018  Powerwashing alone does not take the red dirt stains out. Why are red clay stains so hard to clean from concrete and masonry? Possibly because what gives the reddish color of the dirt is an iron oxide or better known as rust, which is highly insoluble in water. In fact, iron oxides are often used as inexpensive earth tone pigments in coatings, paints and colored concrete.
