Picolinate-based acyclic ligand for rare earth element extraction and separation

Key Points

• The aim is to evaluate an acyclic chelator for its selective extraction and separation of rare earth elements.
• Investigated the performance of the acyclic chelator in extracting rare earth elements.
• Conducted tests on mixed rare earth element oxalates and samples from electronic waste.
• Analyzed the selectivity of the chelator in various conditions.
• The acyclic chelator effectively dissolved mixed rare earth element oxalates.
• It demonstrated a high capacity for direct separation from electronic waste.
• Results suggest improved efficiency compared to traditional methods.
