Tentacle carrier for immobilization of potato phenoloxidase and its application for halogenophenols removal from aqueous solutions

► We synthesized novel immobilization carrier from reused DEAE-cellulose. ► We used it for immobilization of PPO through coordinative bonding with copper ions. ► Immobilized PPO showed better characteristics than soluble PPO. ► TC-PPO removed over 90% of halogenophenols at concentration of 100 mg/L.
