Possible surface complexation reactions between iron oxides and dissolved SiO2
| Reaction | Reference | |
|---|---|---|
| ≡FeOH + Si(OH)4 → ≡FeSiO(OH)3 + H2O | (1) | 11, 12, 30 |
| ≡FeOH + Si(OH)4 → ≡FeSiO2(OH)2− + H2O + H+ | (2) | 11, 12, 30 |
| ≡FeOH + Si2O2(OH)5− + H+ → ≡FeSi2O2(OH)5 + H2O | (3) | 12 |
| ≡FeOH + Si2O2(OH)5− → ≡FeSi2O3(OH)4− + H2O | (4) | 12 |
| 2 ≡FeOH + Si(OH)4 → ≡Fe2O2Si(OH)2 + 2 H2O | (5) | 18, 28 |
| 2 ≡FeOH + 3 Si(OH)4 → ≡Fe2H6-nSi3O10n− + n H+ + 4 H2O | (6) | 29 |
