What is the temperature effect on zeta potential?
My problem was assigned by my teacher for the final exam preparation: "When the temperature is increased, and given in this temperature range, there is no desorption of potential-determining ions on the surface of colloidal particles occurs, we will have:
A. Zeta potential increases, surface potential decreases
B. Zeta potential and surface potential remain constant
C. Zeta potential decreases, surface potential remains constant
D. Zeta potential and surface potential both increase
*Thought: It is stated in the below publishment that the zeta potential decreases while temperature is increased at low salinity (0.01M NaCl). The opposite trend could be seen for high salinity (0.5M NaCl).
