Montmorillonite/Carboxymethylated Cellulose Composite Beads via Blending Method: Column Adsorption Behavior and Mechanism for Trimethoprim at Low Concentrations

Key Points

• This research aims to develop composite beads for the effective removal of trimethoprim from water at low concentrations.
• Developed montmorillonite/carboxymethylated cellulose composite beads through a blending method.
• Conducted column adsorption experiments to assess the behavior of the composite beads.
• Analyzed the mechanism of trimethoprim adsorption in aquatic settings.
• Demonstrated that the composite beads significantly improved trimethoprim removal compared to conventional adsorbents.
• Outlined the optimal conditions for adsorption efficiency at low trimethoprim concentrations.
