Figure 10From: Surface complexation model for strontium sorption to amorphous silica and goethiteRegression of log K"ii,m versus rx,m for the formation of (>SOH)2(>SO-)2_MOH+, (>SOH)2(>SO-)2_M2+, and >SO-_MOH+. Log K"ii,m are derived from regression y-intercepts in Figure 9. The "tet" prefix refers to the tetranuclear surface sites.Back to article page
