From: Surface complexation model for strontium sorption to amorphous silica and goethite
Comparison of experimental and model results for strontium sorption to goethite in 10-6 to 10-4 M Sr(NO3)2 and 0.1 M NaNO3 solutions with dissolved carbonate (A-C). Symbols are the experimental data, solid lines are predictions made with the strontium surface complexation model (Table 9), dashed lines represent ± 0.3 uncertainty in log K for all strontium surface complexation reactions.
