The aqueous geochemistry of the rare earth elements and yttrium. Part XI. The solubility of Nd(OH) 3 and hydrolysis of Nd 3+ from 30 to 290 °C at saturated water vapor pressure with in-situ pH m measurement
Very interesting is the behaviour of certain trace metals in the waters of anoxic basins, in particular at the interface between the oxygen-poor and the overlying oxygenrich waters. Manganese and iron are present in oxygen-rich waters mainly as poorly soluble oxides adsorbed onto particulate matter. When the particulate matter settles across ...
