Bait-and-Anchor Strategy in Dual N/Se-Engineered Resins for Electrostatic-Chelation Cascade Pd(II) Recovery from Extreme Environments

Key Points

• The aim is to develop a method for effectively recovering palladium from complex sources in extreme environments.
• Introduced a heteroatom-engineered resin microsphere (Se-RF) for palladium recovery.
• Evaluated the effectiveness of the Bait-and-Anchor Strategy in the recovery process.
• Investigated the electrostatic-chelation interactions for enhanced capture of Pd(II).
• Achieved selective palladium recovery from challenging sources.
• Demonstrated the effectiveness of dual N/Se-engineered resins in extreme environments.
