Implication

This research demonstrates effective sequential extraction of Nd(III), Th(IV), and Zr(IV) using bromopyrogallol red, suggesting enhanced recovery through diazo-functionalized silica gel.

Key Points

  • The synthesized silica gel with bromopyrogallol red extracts lanthanides and thorium effectively.
  • Enrichment factors reached up to 53 for Nd(III), indicating high extraction efficiency.
  • Developed material remains durable for 18 months, demonstrating potential for repeated use.
  • Sequential separation showcases potential application for metal ion recovery from diverse aqueous solutions.
