Effect of the Presence of Aluminum ions in Iron Solutions on the Formation of Iron Oxyhydroxides (FeOOH) at Room Temperature Under Acidic Environment
Akaganeite Aluminum Hydroxy-aluminum ions Iron hydrolysis Transmission electron microscopy X-ray diffraction
2011/12/29
The hydrolytic behavior of Fe solutions at room temperature under acidic conditions was investigated. In the presence of Al ions, with Cl and NO3 as associated anions, the Fe hydrolysis began almost i...
