Abstract:

Pollution by heavy metals is a serious environmental problem. Lignocellulose offers the advantages of high-capacity storage, renewability, and biodegradability, while offering excellent adsorption performance and being easy to recycle. As such, it is being increasingly used as a magnetic adsorbent for the removal of metal ions from polluted water. Starting with a brief description of magnetic nanomaterials, this review focuses on the preparation of cellulose-, lignin-, and hemicellulose-based magnetic adsorption materials, both domestically and overseas, summarizing and comparing their abilities to adsorb different heavymetal ions. In addition, the adsorption abilities and factors influencing the removal of different heavy metal ions are discussed in detail. Finally, future development directionsfor lignocellulose-based magnetic adsorbents are discussed.

Key words: lignocellulose, magnetic material, adsorbent, heavy metal ion
