Abstract

, cellulose, polyethyleneimine, and chitosan) significantly enhances adsorption performance. Then, a possible adsorption mechanism is discussed in terms of hydrogen bonding, surface complexation, electrostatic interactions, and ion exchange. Finally, the challenges and future directions for developing a high-performance SA-based adsorbent are outlined. This article aims to provide researchers with an in-depth framework for understanding, facilitate the widespread use of SA-based adsorbents in water pollution management, and offer significant insights and guidance for future research.
