This study presents a reusable adsorbent material for industrial wastewater treatment. Double‐network interpenetrating gel beads were prepared via condensation reaction and hydrogen bonding between sodium alginate and collagen, combined with PVA and ion crosslinking. The addition of collagen enhance...
