Adsorption of Polyanion onto Large Alpha Alumina Beads with Variably Charged Surface

Figure 4

Adsorption isotherms of PSS onto -Al₂O₃ of different molecular weight at pH 4 in 0.01 M NaCl (a) and 0.1 M NaCl (b) as a function of the equilibrium PSS concentration. While the points are experimental data, the solid lines fitted the results by general isotherm equation.
