| Outline of Final Research Achievements |
In order to synthesize the homogeneous REE bearing geochemical solid reference material, newly developed sol-gel method was applied. During sol-gel method, adequate amount of aluminum was added into REE bearing solution to form double propoxide as a precursor. It prevents from the aggregation of REE. According to spectroscopic analysis such as FT-IR and XAFS and 3D mapping by LA-ICP-MS, REE in the synthesized material is well dispersed regardless of the number of REE. The synthesized reference materials are highly expected to use for precise quantitative analysis by LA-ICP-MS for the exploration and evaluation of REE deposit.
