The collaboration has resulted in a design and experimental method obtaining precise and accurate analytical data on the content of REY in Fe-Mn deposits
The World Journal of Engineering has recently published a paper on technological developments, using inductively coupled plasma mass spectrometry (ICP-MS), for the determination of economically significant metals including rare-earth elements and Y (REY), Co, Ni and Cu from Fe-Mn deposits of different areas selected along the Atlantic Ocean. The choice of the acquisition mode and other settings of the quadrupole ICP-MS Agilent 7700x allows elimination of spectral overlaps as much as possible and leads to good precision and accuracy of the measurement. The accuracy of the obtained results was controlled by analysis of certified reference materials (CRM) of Fe-Mn nodules of the US Geological Survey – NOD-A-1 and NOD-P-1, as well as the Russian CRM samples of Fe-Mn nodule OOPE 603 (SDO-6) and ore crust OOPE 604 (SDO-7). Statistical processing of the analysis results demonstrated the acceptability of chosen sample preparation technique and ICP-MS tunes for the determination of REY in Fe-Mn deposits.
