Figure 3

(a) Graphical representation of the functionalizing cellulose with PEC. (b) Cellulose (3-carboxypropyl)trimethylammonium chloride ester (CN+), carboxymethylxylan (CMX–), and xylan sulfate (XS–). (c) Sorption isotherms obtained from polyelectrolyte titrations of [CN+CMX–] (a system composed of carboxymethylxylan (CMX–) and cellulose(3-carboxypropyl)trimethylammonium chloride ester (CN+)), [CN+XS–] (a system composed of xylan sulfate (XS–)), and CN+. S, amount of adsorbed charge (μmol/g); C, equilibrium concentration in the solution (μmol/L). Reprinted from ref (28) with permission from the American Chemical Society.
