Preparation of cross-linked 4-vinylpyridine porous resin and study on its HF adsorption performance

Key Points

• The aim is to evaluate the HF adsorption capacity and regenerability of a new cross-linked resin.
• Preparation of WPD-25-1-0.1 cross-linked resin
• Assessment of adsorption capacity for HF
• Evaluation of resin regenerability through thermal N2 purging
• WPD-25-1-0.1 resin shows an HF adsorption capacity of 853 mg g−1
• Resin demonstrates excellent regenerability after thermal N2 purging
