Colloidal hydrous manganese oxide

The Adsorption of Aqueous Metal on Colloidal Hydrous Manganese Oxide... [Pg.82]

T he ability of colloidal, hydrous manganese oxides to adsorb large quantities of aqueous metal ions has been a continuing subject of study since van Bemmelen s work of 1881 (5). While certain aspects of the subject have been well established—e.g., hydrogen ions are released (or hydroxide ions adsorbed) in proportion to the quantity of metal ion adsorbed (11)—there is still confusion as to the details of the mechanism of ion adsorption.

In addition to the soluble chemical species and possible solid phase species described in the previous sections no discussion on speciation can be complete without the consideration of surface species. These include the inorganic and organic ions adsorbed on the surface of particles. Natural systems such as soils, sediments and waters abound with colloids such as the hydrous oxides of iron, aluminium, manganese and silicon which have the potential to form surface complexes with the various cationic and anionic dissolved species (Evans, 1989).
