Microscopic insights into extraction mechanism of copper(II) in ammoniacal solutions studied by X-ray absorption spectroscopy and density functional theory calculation.

A microscopic investigation on the extraction process of copper(II) in ammoniacal solutions has been performed by X-ray absorption spectroscopy (XAS) and density functional theory (DFT) calculation. The structural change of copper(II) species in ammoniacal solution has been derived from X-ray absorption near-edge spectroscopy (XANES) by principal component… (More)
