Local structure of rare earth elements (REE) in marine ferromanganese oxides by extended X-ray absorption fine structure and its comparison with REE in ion-adsorption type deposits

Nagasawa, Makoto*; Qin, H.-B.*; Yamaguchi, Akiko ; Takahashi, Yoshio*

Speciation of rare earth elements (REE) in marine ferromanganese oxides (MFMO) was conducted by extended X-ray absorption fine structure (EXAFS) and sequential extraction to compare the enrichment mechanisms and extraction rates between MFMO and ion-adsorption type deposits, which can be reasonably explained by the formation of inner- and outer-sphere complexes in the two materials for yttrium and other REE.
