Figure 4.28 shows zeta potential of kaolinite in synthetic brine with or without
Ca/ Mg adding Na2CO3. Adding 6.0×10'4 M Na2CO3, pH of the brine increases
from 8.3 to 8.9. The blue dashed curve shows the calculated zeta potential of
kaolinite without Ca/ Mg. The red solid curve shows the calculated zeta potential
of kaolinite with Ca/ Mg, with equilibrium Ca2+ concentration calculated from
CaCO3 solubility product.

Figure 4.28 Kaolinite zeta potential in synthetic brine adding Na2CO3, pH 8.3 - 8.9
In the brine without Ca/ Mg, zeta potential change of kaolinite is around 15
mV∕mM. In the brine with Ca/ Mg, zeta potential change of kaolinite is around 20
mV∕mM. The precipitation of Ca2+ ion can make kaolinite zeta potential more
