This example demonstrates the pH-dependence of the binding of a ligand (A-) to a hydrous oxide using a non-electrostatic surface complexation model. The reaction parameters are based on Example 9.3b (page 545) in Stumm and Morgan (1996). Figure 1 compares the simulation results to the original calculations.
