Separation of lattice-incorporated Cr( vi ) from calcium carbonate by converting microcrystals into nanocrystals via the carbonation pathway based on the density functional theory study of incorporation energy

Calcium carbonate easily allows foreign ions, such as Cr( vi ), to incorporate into its lattice, leading to the long-term slow release of heavy metals and consequent environmental risk. Although CaCO 3 is one of the major minerals in Cr-containing solid waste, little is known regarding the chemical...
