Determination of the host phase of rare earth elements in natural carbonate using X-ray absorption near-edge structure
rare earth elements yttrium XANES carbonate
2017/8/9
The Y K-edge X-ray absorption near-edge structure (XANES) spectra of various materials were measured to investigate whether rare earth elements (REEs) are incorporated in carbonate phase or in other m...
The Effect of Acid Digestion on the Recoveries of Trace Elements: Recommended Policies for the Elimination of Losses
Open wet digestion losses recovery elimination trace elements differential pulse polarography
