Effect of iron oxide on phosphate sorption by calcite and ...

Pure calcite (AR grade CaCO 3) was treated with ferrous perchlorate solution to give a surface coating of iron (Fe) oxide.Maximum sorption (x m) of phosphate (P) by the calcite increased from 18.2 to 160 mg P kg −1 as the amount of coating increased from 0.00 to 16.0 g Fe 2 O 3, kg −1 CaCO 3.Evidence for Fe oxide coatings on carbonate minerals in two Sudanese soils was obtained by optical ...

There are two main uses for hydrochloric acid: removing carbonates like calcite that often are the last minerals to form in a pocket and therefore obscure other mineral crystals, and the more aggressive removal of iron oxide rust stains (faster than oxalic acid).

Reactions of zinc with iron-oxide coated calcite surfaces ...

Both iron oxides and carbonate minerals, such as calcite, can sorb zinc (Zn), and therefore are important in controlling the solution concentration and availability of Zn to plants growing in calcareous soil. When present together, interactions between these components affect their sorption behaviour. Changes in the reactions of Zn with calcite at alkaline pH were investigated, as the calcite...

Fe-oxide concretions formed by interacting carbonate and ...

Iron oxide concretions have slightly lower δ 56 Fe (~ −1.5‰) compared with Fe oxides in the matrix of the Navajo Sandstone (~ +0.3‰). In the previous study, the difference of Fe isotope values was explained by reduction of Fe in the iron oxide source and some subsequent oxidation.
