Abstract
This study developed a magnetic bacterial cellulose (MBC) nanocomposite by integrating Fe3O4 nanoparticles into bacterial cellulose to enhance its adsorption capacity and enable magnetic separation. The composite achieved a maximum Pb²+ adsorption capacity of 81.9 mg/g under optimal conditions (pH 5.5, 40 °C, 120 min), outperforming many conventional adsorbents. Reusability tests showed that MBC retained 36.05% of its adsorption capacity after five cycles, demonstrating its durability for water treatment. The materialâs biodegradability and high efficiency provides a sustainable solution for mitigating heavy metal pollution, highlighting its potential for practical environmental applications.
