Figure 2From: Surface complexation model for strontium sorption to amorphous silica and goethiteΔGr for final solution compositions with respect to strontianite (SrCO3) in which both dissolved strontium and carbonate were measured from amorphous silica (A) and goethite (B) suspensions. Solutions are supersaturated when ΔGr is > 0 and undersaturated when ΔGr < 0.Back to article page
