assuming НСОз’ ion adsorption is closer to the experiment data than the curve
without assuming НСОз’ ion adsorption.

From zeta potential result, anions SO4²’ or HCO3^ can adsorb on positively
charged surface sites and make kaolinite zeta potential more negative.

4.3.5.3. Adsorption effect of cations Ca²⁺ and Mg²⁺

Synthetic brine contains cations Ca²⁺ and Mg²⁺. The negatively charged Al/

Si sites -AO’ can adsorb Ca/ Mg ions and become positively charged.
