Adsorption properties of cross-linked cellulose-epichlorohydrin polymers in aqueous solution

- Cellulose was cross-linked with epichlorohydrin at variable composition.
- Tunable physical properties are evidenced by materials characterization methods.
- Cross-linked cellulose has greater uptake than cellulose with carboxylate anions.
- Cross-linked polymers show molecular selective uptake in solution at equilibrium.
- Micropore domains of cross-linked polymers are active adsorption sites.
