Abstract: Our study investigates the interaction between multi-component rare earth element (REE; La, Ce, Pr, Nd, Dy)-bearing aqueous solutions and vivianite (Fe32+(PO4)2·8H2O) grains under hydrothermal conditions (50–165 °C). The results revealed the solution-mediated, progressive oxidation and… read more here.
