Summary
India possesses significant rare earth element (REE) resources, primarily in monazite sands. Analytical methods were developed to determine REE in seawater and high-purity materials, crucial for future standard reference materials.
Area of Science:
- Geochemistry
- Analytical Chemistry
Background:
- India ranks third globally in rare earth element (REE) resources.
- These resources are predominantly found in monazite sands along India's coasts.
Purpose of the Study:
- To develop analytical methodologies for determining REE concentrations.
- To analyze REE in seawater and high-purity materials.
- To provide a foundation for future standard reference materials.
Main Methods:
- Development of analytical techniques for REE determination.
- Application of these techniques to seawater samples.
- Application of these techniques to high-purity materials.
Main Results:
- Established analytical methodologies for REE quantification.
- Demonstrated the feasibility of analyzing REE in complex matrices like seawater.
- Provided data relevant to high-purity material characterization.
Conclusions:
- The developed analytical methods are vital for characterizing India's REE resources.
- These methodologies are essential for creating future standard reference materials for environmental and industrial applications.
- This work supports the accurate assessment and utilization of REE deposits.
