Preparation of new class composite adsorbent for enhanced palladium(II) detection and recovery

- Novel ligand based composite adsorbent was developed for enhanced Pd(II) capturing.
- Influenced by pH, initial concentration, shaking time, diverse ions were evaluated.
- Ultra-trace Pd(II) was detected and recovered with specific color formation.
- The adsorbent was reused in many cycles without damage to cage cavities.
