Preparation of Reference Material for Deep-Sea Rare Earth-Enriched Sediments in the Pacific Ocean
Rare earth elements play a key role in industrial developments.However,there are few sediment reference materials of rare-earth elements and yttrium(together called REYs)worldwide.A deep-sea sediment certified material rich in rare earth elements has been developed and evaluated on the special protocol of a certified reference material,and 62 components of major,minor and trace components in the deep-sea rare earth-enriched sediments were determined.Reference Material for Deep-sea Rare Earth-enriched Sediments in the Pacific Ocean has now been certified as GBW07590.The BRIEF REPORT is available for this paper at http://www.ykcs.ac.cn/en/article/doi/10.15898/j.ykcs.202303130033.
